Solution
The correct option is B structural
Positional isomerism is a type of structural isomerism. Positional isomerism is also called as regioisomerism. Positional isomers have
same molecular formula, but they differ in the position of the
functional group.Thus, 1-hexanol (CH3−CH2−CH2−CH2−CH2−CH2−OH), 2-hexanol (CH3−C|OHH−CH2−CH2−CH2−CH3) and 3-hexanol (CH3−CH2−C|OHH−CH2−CH2−CH3) are positional isomers. They differ in the position of
−OH group.
