Study Notes
Intermolecular and Interatomic Forces
- Intermolecular forces act between molecules and determine a substance's physical properties.
- Polar molecules exhibit electronegativity differences between atoms, causing shared electron pairs to spend more time near the more attractive atom.
- This electronegativity difference creates a dipole with partially positive (δ+) and partially negative (δ−) charges, defining these molecules as dipoles.
Types of Intermolecular Forces
- Ion-Dipole Forces: Occur between an ion and a polar molecule, where positive ions attract the negative pole, and negative ions attract the positive pole.
- Ion-Induced Dipole Forces: Occur between ions and nonpolar molecules, inducing a temporary dipole in the nonpolar molecule, leading to a weak, short-lived attraction.
- Dipole-Dipole Forces: Occur between polar molecules, with the positive pole of one molecule attracting the negative pole of another. Hydrogen bonding is a special case.
- Induced Dipole Forces (London Dispersion Forces): Occur in nonpolar molecules due to temporary, uneven electron distribution, creating temporary dipoles.
- These temporary dipoles induce dipoles in adjacent molecules, resulting in a weak attraction.
- These forces are present in all molecules but are the only forces in nonpolar molecules.
- Dipole-Induced Dipole Forces: Occur when a polar molecule induces a dipole in a nonpolar molecule.
- Example: Chloroform (CHCl3) in carbon tetrachloride (CCl4).
Hydrogen Bonds
- Occur when hydrogen is covalently bonded to highly electronegative atoms like oxygen, nitrogen, or fluorine.
- The hydrogen atom of one molecule is attracted to the electronegative atom of another, creating a relatively strong intermolecular force.
- Example: Water molecules, where hydrogen bonds form between the hydrogen atom of one molecule and the oxygen atom of another.
Differences Between Intermolecular and Interatomic Forces
- Intermolecular Forces: Occur between molecules, including dipole-dipole forces, hydrogen bonds, and London dispersion forces, and are generally weaker than interatomic forces.
- Interatomic Forces (Chemical Bonds): Occur within molecules, including covalent, ionic, and metallic bonds, and are stronger than intermolecular forces.
Properties Affected by Intermolecular Forces
- Phase of Matter: Strong intermolecular forces result in solids; weak intermolecular forces result in gases.
- Melting and Boiling Points: Substances with strong intermolecular forces have high melting and boiling points; substances with weak intermolecular forces have low melting and boiling points.
- Viscosity: Substances with strong intermolecular forces are more viscous (resistant to flow). Viscosity is defined as a liquid's resistance to flow
- Density: Solids are often the densest phase due to strong intermolecular forces. Density is defined as mass per unit volume
- Thermal Expansion: Substances expand when heated due to increased molecular movement.
- Thermal Conductivity: Metals have high conductivity due to free electrons. Thermal conductivity is defined as the ability of a substance to conduct heat.
Investigation of Intermolecular Forces
- Evaporation: Substances with weaker intermolecular forces evaporate faster.
- Surface Tension: Stronger intermolecular forces result in higher surface tension.
- Solubility: Substances dissolve in solvents with similar intermolecular forces ("like dissolves like").
- Boiling Point: Substances with stronger intermolecular forces have higher boiling points.
- Capillarity: Substances with stronger intermolecular forces travel further up a narrow tube.
Molecular Size and Intermolecular Forces
- Larger molecules have stronger intermolecular forces.
- In organic compounds like alkanes, increasing the number of carbon atoms increases the boiling and melting points due to stronger intermolecular forces.
The Chemistry of Water
- Water's unique properties arise from its microscopic structure, molecular shape, polar nature, and intermolecular forces.
- It consists of two hydrogen atoms bonded to a central oxygen atom with two lone pairs of electrons, resulting in a bent shape and polar molecule.
- Water molecules are held together by hydrogen bonds.
Unique Properties of Water
- Specific Heat: Water has a high specific heat, absorbing a lot of energy before its temperature changes significantly, due to the need to disrupt hydrogen bonds.
- Specific heat is the amount of heat energy needed to increase the temperature of a unit mass of a substance by one degree.
- Regulates environmental temperatures, with large water bodies moderating climate by storing and releasing heat.
- High specific heat also plays a critical role in biological systems, helping to maintain stable temperatures within organisms.
- Absorption of InfraRed Radiation: Water absorbs infrared radiation from the sun, acting as a heat reservoir to moderate Earth’s climate.
- The absorption of infrared radiation is due to the vibrational and rotational movements of water molecules, which can trap and store heat energy.
- Water's ability to absorb and store heat makes it an effective climate buffer, preventing extreme temperature changes.
- Melting Point and Boiling Point: Water has a melting point of 0°C and a boiling point of 100°C at standard pressure.
- This large temperature range allows water to exist as a liquid over a wide range of temperatures, which is crucial for life on Earth.
- The significant difference between the melting and boiling points of water is due to the strong hydrogen bonds that must be overcome to change phases.
- The melting and boiling points of water are higher than those of many other molecular compounds of similar size and mass due to the presence of hydrogen bonds.
- These strong intermolecular forces require more energy to break, leading to higher phase transition temperatures.
- Ensures that water remains in the liquid state under most environmental conditions, supporting various biological and ecological processes.
- High Heat of Vaporisation: Water has a high heat of vaporisation (40.65 kJ·mol−1), requiring significant energy to change from liquid to gas, essential for maintaining liquid water on Earth.
- Heat of vaporisation is the energy needed to change a given quantity of a substance into a gas.
- This property is vital for maintaining liquid water on Earth and preventing the evaporation of bodily water.
- The high heat of vaporisation of water is a result of the strong hydrogen bonds between water molecules.
- This property is essential in regulating body temperature through perspiration.
- When sweat evaporates from the skin, it absorbs a large amount of heat from the body, providing a cooling effect.
- Less Dense Solid Phase: Ice is less dense than liquid water, due to hydrogen bonding creating an open hexagonal structure.
- While other materials contract when they solidify, water expands.
- This allows ice to float, insulating water below and enabling aquatic life to survive in cold climates.
- If ice sank, eventually all ponds, lakes, and even the oceans would freeze solid as soon as temperatures dropped below freezing, making life as we know it impossible on Earth.
- During summer, only the upper few meters of the ocean would thaw.
- Water's lower density in its solid form is due to the hydrogen bonding that creates an open hexagonal structure in ice.
- This structure takes up more space than the more closely packed arrangement of molecules in liquid water, resulting in a lower density.
- The floating ice insulates the water beneath, preventing entire bodies of water from freezing solid and providing a habitat for aquatic life even in cold climates.
- This property also has significant ecological implications, as it influences the thermal stratification and mixing of water bodies.
The Interactions of Water with Various Substances
- Water is an excellent solvent for ionic and polar substances.
- When ionic compounds dissolve, ions are surrounded and stabilized by water molecules (hydration).
- Water's polarity allows it to interact with and dissolve various substances.
- The partially positive hydrogen atoms in water molecules are attracted to negatively charged ions, while the partially negative oxygen atoms are attracted to positively charged ions.
- This interaction disrupts the ionic bonds in the solute, allowing the ions to disperse uniformly throughout the solution.
- Water dissolves many polar covalent compounds due to hydrogen bonding (e.g., ethanol and sugar).
- Nonpolar substances do not dissolve well in water.
- "Like dissolves like" - solvents dissolve solutes with similar polarity.
- Water's solvent properties are essential for biological functions, enabling transport and reactions in living organisms.
- In plants, water transports minerals from the soil and nutrients produced in photosynthesis.
- In animals, water carries oxygen, nutrients, and hormones to cells and removes metabolic waste products.
- It also supports environmental processes like nutrient distribution in soil and aquatic ecosystems.
- Water's role as a solvent is also crucial in environmental processes.
- It enables the distribution of nutrients in soil.
- Supports aquatic ecosystems by dissolving oxygen and carbon dioxide.
- Participates in the weathering and erosion of rocks.
- Water's ability to dissolve a wide range of substances makes it integral to many natural and human-made processes.
