Study Notes
Carbon
- Carbon has 4 valence electrons
- Carbon forms the backbone of many organic molecules
- Carbon-containing molecules are organic molecules
- Carbon forms covalent bonds
- Carbon bonding involves hybridization of orbitals
- Carbon forms different shapes depending on bonding (tetrahedral, trigonal planar, etc.)
Organic Molecules
- Organic molecules contain carbon
- Organic molecules show diverse structures and properties
- Different structures impact properties (e.g., isomers)
Bond Types
- Covalent bonds (sharing electrons)
- Single bonds allow for rotation
- Double bonds do not allow for rotation
- Triple bonds are linear
Isomers
- Isomers have the same chemical formula but different structures
- Structural isomers have different bonding arrangements
- Stereoisomers have different spatial arrangements around a central bond (geometric/cis-trans, enantiomers)
- Geometric isomers differ in the arrangement around a double bond (cis-trans)
- Enantiomers are mirror images of each other
Functional Groups
- Hydroxyl (-OH): polar covalent bond, hydrophilic, alcohols
- Carbonyl (C=O): aldehydes, ketones
- Carboxyl (-COOH): acids, increase acidity
- Amino (-NH2): bases, increase pH
- Sulfhydryl (-SH): cysteine, disulfides
- Methyl (—CH3): nonpolar, hydrophobic
- Phosphate (-PO4): reacts with water, energy transfer
Other Notes
- Silicon is in the same family as carbon but has different reactivity with oxygen
- Hydrocarbons are nonpolar molecules
