Detailed Solution

Positional isomers are those isomers in which the molecular formula and carbon skeleton of the compound is same but the position of the functional group is different in each isomer.

3⁰ butyl is tertiary butyl where -OH is attached to the tertiary carbon atom.

Isobutyl alcohol also has a tertiary carbon skeleton but -OH group is attached to one of the terminal carbon atom.
