Hydrocarbons *Compounds with just Hydrogen and Carbon

Reference Tables used with Organic Chemistry Table P Table Q

Types of Hydrocarbons: Alkanes *have single bonds between carbons *end in “ane” * formula = CnH2n+2 methane ethane propane

Branched Chain Alkanes Need at least 4 carbons Isomers: same molecular formula but different structural formulas C5H12

Types of Hydrocarbons: Alkenes: *have one double bond between carbons *end in “ene” * formula = CnH2n ethene propene 1-butene 2-butene

Types of Hydrocarbons: 3. Alkynes: *have one triple bond between carbons *end in “yne” * formula = CnH2n-2 ethyne propyne

A group of compounds that vary by a common increment Homologous Series: A group of compounds that vary by a common increment Table Q ane = Single bond ene = Double bond yne = Triple bond

Derivatives of Hydrocarbons One or more atoms replace Hydrogen in the hydrocarbon Alkyl Group: *an alkane with a missing Hydrogen Methane CH4 CH3 Ethane C2H6 Ethyl C2H5

2-methyl propane

Derivatives of Hydrocarbons Functional Group: *a group of elements that determine the type of compound Table R Alcohol - Base – NaOH not a functional group
