Study Notes
Organic Compounds and Carbon Identification
- Carbon atoms in organic compounds may be numbered based on proximity to the most oxidized group, where the α-carbon is adjacent to this group.
Types of Chemical Bonds
- Ionic Bonds: Involve complete electron transfer; results in positively and negatively charged ions.
- Covalent Bonds: Involves sharing of electrons and can be polar (unequal sharing) or nonpolar (equal sharing).
Chemical Reactions
- Elimination Reactions: Reverse of addition reactions, leading to the formation of double bonds.
- Substitution Reactions: One substituent is replaced by another within the compound.
- Rearrangement Reactions: Structural change in a compound without a change in molecular formula.
Organic Compound Properties
- Intermolecular Forces (IMFA): Influences properties such as solubility; weak compared to intramolecular forces.
- Molecule Polarity: Determined by geometry and individual bond polarities, affecting how molecules interact.
Reaction Intermediates
- Carbocation: A positively charged carbon ion, formed during some reactions.
- Carbanions: A negatively charged carbon ion.
- Free Radicals: Contains unpaired electrons, highly reactive species.
Types of Organic Reactions
- Addition Reactions: Characteristic of unsaturated compounds, lead to the disruption of multiple bonds.
Intermolecular Forces of Attraction
- Physical properties such as solubility depend on IMFA; the principle “like dissolves like” applies to solubility based on polarity.
Stereoisomers
- Diastereomers: Include cis (same side) and trans (opposite sides) isomers, significant in lipid studies.
- Enantiomers: Non-superimposable mirror images, important in biochemistry.
- Epimers: Differ at only one asymmetric carbon’s hydroxyl group.
Importance of Biomolecules
- Major classes include Lipids, Proteins, Carbohydrates, and Nucleic Acids.
- Carbohydrates: Monosaccharides link via O-glycosidic or N-glycosidic bonds to form larger molecules.
- Nucleic Acids: Composed of purines and pyrimidines; nucleosides link sugars to nitrogenous bases.
Historical Context
- Urea synthesis from ammonium cyanate in 1828 demonstrated that organic compounds could be formed from inorganic materials, challenging the belief that organic compounds only came from living organisms.
Functions of Nucleotides
- Nucleotides serve various roles including energy storage (e.g., ATP) and forming parts of coenzymes (e.g., NAD+).
