What is "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:

• 1-Bromopentane
• 2-Bromopentane
• 3-Bromopentane

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:

• 1-bromo-2-methylbutane
• 2-bromo-2-methylbutane
• 2-bromo-3-methylbutane
• 1-bromo-3-methylbutane

For 2,2-dimethylpropane, there is only one possible brominated derivative:

• 1-bromo-2,2-dimethylpropane
