Answer» SOLUTION :Compounds having the same molecular formula but different STRUCTURAL formulae are known as structural isomers. Examples : (1) Structural isomers of butane `(C_(4)H_(10))` :  (2) Structural isomers of pentane `(C_(5)H_(12))` : (a) `CH_(3)-CH_(2)-CH_(2)-CH_(2)-CH_(3)`n-Pentane (Pentane) (b) `CH_(3)-underset(CH_(3))underset(|)CH-CH_(2)-CH_(3)`Isopentane (2-Methylbutane) ( c ) `CH_(3)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)C-CH_(3)`Neopentane (2, 2-Dimethyl-propane) (3) Structur5al isomers of hexane `(C_(6)H_(14))` : (a) `CH_(3)-CH_(2)-CH_(2)-CH_(2)-CH_(2)-CH_(3)`n-Hexane (Hexane) (b) `CH_(3)-underset(CH_(3))underset(|)CH-CH_(2)-CH_(2)-CH_(3)`2-Methylpentane ( c ) `CH_(3)-CH_(2)-underset(CH_(3))underset(|)CH-CH_(2)-CH_(3)`3-Methylpentane (d) `CH_(3)-underset(CH_(3))underset(|)CH-underset(CH_(3))underset(|)CH-CH_(3)`2, 3-Dimethylbutane (e) `CH_(3)-underset(CH_(3))underset(|)overset(CH_(3))overset(|)C-CH_(2)-CH_(3)`2,2-Dimethylbutane |
