Study Notes
###Â Chemical Bonds
- Ionic bonds occur when electrons transfer from one atom to another resulting in the production of charged atoms called ions.
- Covalent bonds occur when electrons are shared between two atoms.
- Covalent bonds can be polar or non-polar.
Properties of Organic Compounds
- Influenced by intermolecular forces of attraction, molecular geometry, and structural effects.
- Structural effects include, orbital hybridization, steric effects, inductive effects, resonance, and hyperconjugation.
###Â Molecular Polarity
- Based on the distribution of electrons across the entire molecule.
###Â Intermolecular Forces of Attraction (IMFA)
- Attractive forces between molecules which must be overcome during melting, evaporation, and sublimation.
- Types of IMFA:
- London Dispersion Forces (LDF): Present in all substances, only IMFA present in non-polar substances and noble gases.
- Dipole-Dipole Forces: Present only in polar compounds, strength increases with increased molecule polarity.
- Hydrogen Bonding: Strong IMFA, a special type of dipole-dipole force.
- Ion-Ion Forces: Present in ionic organic compounds, strong due to electrostatic lattice forces.
Isomerism
- Compounds with the same molecular formula but different structural formulas.
- Two types:
- Structural Isomerism: Variations in the bonding arrangement of atoms or groups.
- Skeletal isomerism: Different carbon skeleton.
- Positional isomerism: Same functional group with different positions.
- Functional isomerism: Same molecular formula with different functional groups.
- Stereoisomerism: No variations in bonding arrangement, only in orientation in space.
- Geometric isomerism: Variations in the spatial arrangement of atoms or groups due to the presence of a double bond or a ring.
- Cis: Functional groups on the same side of a double bond (generally has a bent structure).
- Trans: Functional groups on opposite sides of a double bond (generally has a linear structure).
- Conformational isomerism: Rotations around single bonds that result in different spatial arrangements.
- Geometric isomerism: Variations in the spatial arrangement of atoms or groups due to the presence of a double bond or a ring.
- Structural Isomerism: Variations in the bonding arrangement of atoms or groups.
Origins of Life
- Vitalism theory: Living organisms do not behave according to the known laws of physics and chemistry.
- Evidence against vitalism: Urea, an organic compound, was synthesized by heating the inorganic compound ammonium cyanate in 1828.
- This evidence suggests that biochemical processes, such as formation of organic compounds, can also occur outside of living organisms.
