Name the 5 Different Structural Isomers of Hexane

Answer: There are five isomers of hexane:

Hexane,  CH3CH2CH2CH2CH2CH3, is a six carbon- atom straight chain.

2-Methylpentane, which is also known as Isohexane, (Formula: CH3CH(CH3)CH2CH2CH3), is a five-carbon chain which has one methyl branch on the second carbon.

3-Methylpentane, CH3CH2CH(CH3)CH2CH3, is a five-carbon chain which has one methyl branch on the third carbon.

2,3-Dimethylbutane, CH3CH(CH3)CH(CH3)CH3, is a four-carbon chain having one methyl branch on the second and third carbon.

2,2-Dimethylbutane (neohexane), CH3C(CH3)2CH2CH3, is a four-carbon chain having two methyl branches on the second carbon.
