Study Notes
Positive Mindset
- Focus on positive aspects of life.
- Surround yourself with optimistic individuals.
- Engage in positive self-talk for mental well-being.
Intramolecular and Intermolecular Forces
- Two types of forces in molecules: intramolecular and intermolecular.
- Intramolecular forces hold atoms together within a molecule.
- Intermolecular forces exist between separate molecules.
Intramolecular Forces
- Stronger than intermolecular forces, responsible for chemical bonds.
- Determine chemical behavior of substances.
- Types include:
- Ionic Bonds: Formed by complete transfer of electrons from metals to nonmetals.
- Covalent Bonds: Involves sharing electrons, can form polar or nonpolar covalent bonds.
Types of Intermolecular Forces
- Weaker than intramolecular forces, affect physical properties and state of matter.
- Types include:
- Dipole-Dipole Forces: Attraction between opposite charges of polar molecules.
- London Dispersion Forces (LDF): Present in all molecules; stronger in larger molecules due to more electrons.
- Hydrogen Bonding: Special type of dipole-dipole attraction involving hydrogen bonded to N, O, or F.
Key Comparisons
- Intramolecular forces:
- Stronger forces that hold atoms together.
- Includes covalent, ionic, and metallic bonds.
- Intermolecular forces:
- Weaker forces that act between molecules.
- Inform the physical states (solid, liquid, gas) and properties of substances.
London Dispersion Forces
- Example: Bromine (Br2) has stronger LDF than chlorine (Cl2) due to more electrons, resulting in higher boiling point.
Common Questions
- Intramolecular force formed by shared electrons is a Covalent bond.
- Intramolecular force that generates opposite charged ions is an Ionic bond.
- Covalent bond type for slightly different electronegativities is a Polar covalent bond.
- Covalent bond between similar electronegativities is a Nonpolar covalent bond.
- Attractive force between polar molecules' positive and negative ends is Dipole-Dipole.
- Attractive force in ionic compounds in polar liquids is Ion-Dipole.
- Compounds without hydrogen bonds include H2S.
- Dipole-dipole attractions can be found in H2O.
- Strongest London dispersion forces are in Br2.
- Compound with only London dispersion forces is CO2.
