Senior High School General Chemistry 2 School Year: 2024 - 2025 Matter is anything that takes up space and can be weighed. In other words, matter has volume and mass. Senior High School General Chemistry 2 School Year: 2024 - 2025 Senior High School General Chemistry 2 School Year: 2024 - 2025 Kinetic Molecular Theory explains how particles (atoms or molecules) move in different states of matter. Senior High School General Chemistry 2 School Year: 2024 - 2025 What are the two types of molecular forces? Senior High School General Chemistry 2 School Year: 2024 - 2025 Intramolecular Forces of Attraction – are the forces that hold atoms together within a molecule. Senior High School General Chemistry 2 School Year: 2024 - 2025 Intermolecular Forces of Attraction – are forces that exist between molecules. Senior High School General Chemistry 2 School Year: 2024 - 2025 Senior High School General Chemistry 2 School Year: 2024 - 2025 Structure of Hydrogen Chloride Senior High School General Chemistry 2 School Year: 2024 - 2025 TYPES OF INTRAMOLECULAR FORCES OF ATTRACTION 1. IONIC BOND – is formed by the complete transfer of valence electron (s) between atoms. Senior High School General Chemistry 2 School Year: 2024 - 2025 TYPES OF INTRAMOLECULAR FORCES OF ATTRACTION 2. COVALENT BOND – This bond is formed between atoms that have similar electronegativities – the affinity or desire for electrons. Because both atoms have similar affinity for electrons and neither has a tendency to donate them, they share electrons in order to achieve octet configuration and become more stable. Senior High School General Chemistry 2 School Year: 2024 - 2025 COVALENT BONDING a. Non-Polar Covalent Bond – is formed between same atoms or atoms with very similar electronegativities – the difference in electronegativity between bonded atoms is less than 0.5. Senior High School General Chemistry 2 School Year: 2024 - 2025 COVALENT BONDING b. Polar Covalent Bond – is formed when atoms of slightly different electronegativities share electrons. Senior High School General Chemistry 2 School Year: 2024 - 2025 TYPES OF INTERMOLECULAR FORCES OF ATTRACTION 1. DIPOLE – DIPOLE FORCES – forces are attractive forces between the positive end of one polar molecule and the negative end of another polar molecule. Senior High School General Chemistry 2 School Year: 2024 - 2025 TYPES OF INTERMOLECULAR FORCES OF ATTRACTION 2. HYDROGEN BONDING – this is a special kind of dipole-dipole interaction that occurs specifically between a hydrogen atom bonded to either an oxygen, nitrogen, or fluorine atom. Senior High School General Chemistry 2 School Year: 2024 - 2025 TYPES OF INTERMOLECULAR FORCES OF ATTRACTION 3. LONDON DISPERSION FORCES – the weakest of the intermolecular forces and exist between all types of molecules, whether ionic or covalent – polar or non- polar. The more electrons a molecule has, the stronger the London dispersion forces are. Senior High School General Chemistry 2 School Year: 2024 - 2025 Water is everything! Senior High School General Chemistry 2 School Year: 2024 - 2025 PROPERTIES OF WATER Water as a solvent Cohesion and Adhesion Density Specific Heat Capacity Heat of Vaporization Senior High School General Chemistry 2 School Year: 2024 - 2025 Water as a solvent Water molecules are also attracted to other polar molecules and to ions. A charged or polar substance that interacts with and dissolves in water is said to be hydrophilic: hydro means “water”, and philic means “loving”. Senior High School General Chemistry 2 School Year: 2024 - 2025 Cohesion and Adhesion Cohesion – refers to the attraction of molecules for other molecules of the same kind, and water molecules have strong cohesive forces thanks to their ability to form hydrogen bonds with one another. Senior High School General Chemistry 2 School Year: 2024 - 2025 Cohesion and Adhesion Adhesion – refers to the attraction of molecules for other molecules of a different kind. Senior High School General Chemistry 2 School Year: 2024 - 2025 Senior High School General Chemistry 2 School Year: 2024 - 2025 Density Density is a measure of how compact the mass in a substance or object is. Density of a liquid water Density of ice 1 g/cm^3 0.9168 g/cm^3 Water is in lower density in its solid form due to the way of hydrogen bonds are oriented as if freezes. Senior High School General Chemistry 2 School Year: 2024 - 2025 Senior High School General Chemistry 2 School Year: 2024 - 2025 Specific Heat Capacity It is the amount of heat needed to raise the temperature of one gram of a substance by one degree Celsius. Senior High School General Chemistry 2 School Year: 2024 - 2025 Heat of Vaporization It also takes an unusual amount of heat to vaporize a given amount of water, because hydrogen bonds must be broken in order for the molecules to fly off as gas. Water has a high heat of vaporization – the amount of energy needed to change one gram of a liquid substance to a gas at constant temperature. Senior High School General Chemistry 2 School Year: 2024 - 2025 Try this One! ACTIVITY 1 Learning Objective: Identify kinetic molecular model to intermolecular forces.
