Bromopentane
Bromopentanes are a group of related chemical compounds which are brominated derivatives of pentane. There are three constitutional isomers which are distinguished by the location of the bromine atom: There can also be different connectivity between the 5 carbon atoms. So pentane can either have 5 carbons in a straight chain, or it can be branched. Pentane has two possible branched structures: 2-methylbutane ("isopentane") and 2,2-dimethylpropane ("neopentane"). For 2-methylbutane, the possibilities for combining with bromine are: For 2,2-dimethylpropane, there is only one possible brominated derivative:
