    Straight Chain Alkanes The general formula for an alkane is CnH2n+2 wheren is the number of carbon atoms in the molecule. There are two ways of writing a condensed structural formula. For example‚ butane may be written as CH3CH2CH2CH3 or CH3(CH2)2CH3. Rules for Naming Alkanes * The parent name of the molecule is determined by the number of carbons in the longest chain. * In the case where two chains have the same number of carbons‚ the parent is the chain with the most substituents.

    -ane ending. An alkane can be recognized by its general formula‚ CnH2n+2‚ where n is the number of carbon atoms in the compound. For example‚ C5H12 has five carbon atoms pentane. Each member of the alkane family differs from the next by a — CH2 — group‚ and all the carbons are connected by single bonds. Example 1: Name the following compounds: a. CH4 b. C2H6 or CH3CH3 c.
