Study Notes

Organic Chemistry Overview

  • Organic Chemistry studies carbon compounds, including those not related to life.

Hydrocarbons

  • Saturated Hydrocarbon: Contains only carbon-to-carbon single bonds; most chemically inert.
  • Unsaturated Hydrocarbon: Contains carbon-to-carbon double or triple bonds.

Carbon and Hydrocarbon Types

  • Carbon: Capable of sharing four electrons for stability.
  • Hydrocarbon Molecule: Composed solely of carbon and hydrogen; classified into aliphatic and aromatic.
  • Substituted Hydrocarbon: Hydrogen atoms replaced by functional groups.

Hydrocarbon Classifications

  • Aliphatic Hydrocarbon: Saturated, no benzene, only carbon and maximum hydrogen.
  • Aromatic Hydrocarbon: Contains at least one benzene ring.

Benzene Structure

  • Benzene: A ring of six carbon atoms with alternating single and double bonds.

Hydrocarbon Types with Formulas

  • Alkanes: General formula CnH2n+2; saturated hydrocarbons derived from methane.
  • Cycloalkanes: General formula CnH2n; cyclic saturated hydrocarbons.

Isomerism

  • Structural Isomerism: Identical molecular formulas but differing structures.
  • Cis-trans Isomerism: Geometric isomers differing in 3D arrangement due to restricted rotation.

Functional Groups and Nomenclature

  • Functional Group: Specific atom/group responsible for a molecule's chemical and physical properties; 10 total recognized.
  • Alcohols: Contain hydroxyl group (R-OH); suffix "-ol".
  • Carboxylic Acids: Contain carboxyl group; suffix "-oic acid".
  • Esters: Formed from carboxylic acid and alcohol; suffix "-oate".
  • Aldehydes: Two hydrogen atoms replaced by carbonyl group; suffix "-al".
  • Ketones: Carbonyl group attached to two organic radicals; suffix "-one".
  • Ethers: Two alkyl groups connected to the same oxygen; noted as R-O-R.
  • Amines: Derived from ammonia; prefix "amino-".
  • Amides: Contain a carbonyl-nitrogen bond formed from carboxylic acids and amines.

Carbon Prefixes

  • Meth-: 1 carbon
  • Eth-: 2 carbons
  • Prop-: 3 carbons
  • But-: 4 carbons
  • Pent-: 5 carbons
  • Hex-: 6 carbons
  • Hept-: 7 carbons
