Branched Chain Alkanes The halogens and groups of atoms like carbon, hydrogen, oxygen, nitrogen, sulfur or phosphorus can take the place of a hydrogen in the carbon chain

Organic Nomenclature • Alkanes(CnH2n+2) • Compounds containing all C to C single bonds. • Homologous Series • Methane CH4 • Ethane C2H6 • Propane C3H8 • Butane C4H10 • Pentane C5H12 • Hexane C6H14 • Heptane C7H16 • Octane C8H18 • Nonane C9H20 • Decane C10H22
Cycloalkane (CnH2n) • Isomers of alkenes (CnH2n) • Rings in shape • Contain C to C single bonds
Rules for naming alkanes • Use longest chain. • Number C atoms, starting from the end nearest attachment (side chain or substituent). • Punctuation is important. • Name is one word. • Numbers separated by commas. • Numbers separated from words with hyphens. • If branch is an alkane then the suffix –yl is added. • If more than one of the same branch is present then the Greek prefixes are used (mono-, di-, tri-, tetra-, etc.). • If more than one branch is present they are listed in alphabetical order (Greek prefixes are not used for the ordering). • Halogen branches are the same but w/o –yl suffix (chloro-, bromo-, etc).
