Write long answer on what is Isomer? Explain isomer of hexane.

Explanation:

Hexane has five isomers: Hexane, CH3CH2CH2CH2CH2CH3, a straight chain of six carbon atoms. 2-Methylpentane (Isohexane), CH3CH(CH3)CH2CH2CH3, a five-carbon chain with one methyl branch on the second. ... 2,2-Dimethylbutane (neohexane), CH3C(CH3)2CH2CH3, a four-carbon chain with two methyl branches on the second

HexaneCH3CH2CH2CH2CH2CH3342

3-MethylpentaneCH3CH2CH(CH3)CH2CH3337

2-MethylpentaneCH3CH(CH3)CH2CH2CH3333

2,3-DimethylbutaneCH3CH(CH3)CH(CH3)CH3331

c is the answer because when something is left after something evaporates that shows the chemical change.
