Study Notes
Carbon Compounds
- Carbon forms a vast number of compounds (over 9 million known).
- A naming system categorizes and simplifies these compounds.
- The simplest carbon compound is methane (CH4).
- Straight-chain alkanes (e.g., ethane, propane, butane, pentane) differ by a –CH2– group.
- Chemical formulas show elemental composition, but not atom arrangement.
- Condensed structures better illustrate atom connections; C-H and C-C bonds are implied.
- Structure formulas provide the most detailed atom connectivity.
Functional Groups
- Functional groups impact compound properties.
- Functionality results from different atoms attached to carbon structures. These groups (e.g., -COOH, ketones) change polarity contributing unique reactivities.
- Acetic acid (-COOH) and acetone (ketone) illustrate the impact of functional groups, differing greatly in properties (e.g., melting point, density).
- Size similarities can mask differing properties driven by unique functional groups.
Organic Functional Groups
- Numerous functional groups exist due to carbon's bonding with various elements (H, O, S, N).
- Carbon forms multiple bonds with itself and other atoms, increasing group variety. These varying functional groups are significant to understanding chemical properties.
- In biochemistry, specific functional groups are important (Table 1.3)
- "R" in condensed structural formulas refers to the remainder of the molecule (alkyl group) attached to the functional group.
- Scientists generally use R notation in communicating compound functional groups.
