Bromopentane

Bromopentanes are a group of bromoalkanes consisting of pentane isomers with one or more hydrogen atoms replaced by bromine atoms. They have the formula C5H12–nBrn, where n = 1–12 is the number of bromine atoms. They are colorless liquids.

Monobromopentane
Monobromopentanes are bromopentanes containing one bromine atom, with the formula C5H11Br.

There are three isomers of unbranched monobromopentane:
 * 1-Bromopentane
 * 2-Bromopentane (chiral)
 * 3-Bromopentane

There are four isomers of monobromopentane based on 2-methylbutane:
 * 1-Bromo-2-methylbutane (chiral)
 * 1-Bromo-3-methylbutane
 * 2-Bromo-2-methylbutane
 * 2-Bromo-3-methylbutane (chiral)

2,2-Dimethylpropane has only one monobrominated derivative, 1-bromo-2,2-dimethylpropane, also known as neopentyl bromide.
