Explanation

There are five structural isomers of `C_6H_14 `viz.
(i) `CH_3 - CH_2 - CH_2 - CH_2 - CH_2 - CH_3` n - hexane
(ii) `CH_3 - overset(CH_3) overset(|)CH - CH_2 - CH_2 - CH_3` 2-methylpentane
(iii) `CH_3 - CH_2 - overset(CH_3)overset(|)CH - CH_2 - CH_3` 3- methylpentan
(iv) `CH_3 - underset(CH_3)underset(|)overset(CH_3)overset(|)C - CH_2 - CH_3` 2,2 - dimethylbutane
(v) `CH_3 - overset(CH_3) overset(|)(CH) -overset(CH_3)overset(|)CH - CH_3` 2,3 - dimethylbutane
