Explanation
- The IUPAC name of the first isomer is hexane as it has a linear chain.
- The IUPAC name of the second isomer is 2-methylpentane as it has a chain of five carbons with a methyl group at the second position.
- The IUPAC name of the third isomer is 3-methylpentane as it has a chain of five carbons with a methyl group at the third position.
- The IUPAC name of the fourth isomer is 2,2-dimethylbutane as it has a chain of four carbons with two methyl groups at the second position.
- The IUPAC name of the fifth isomer is 2,3-dimethylbutane as it has a chain of four carbons and two methyl groups at the second and third positions.
