Stability of carbonium ion or carbocation depends on the adjacent alkyl groups. Alkyl groups exhibit electron releasing \(+ I\) effect and hyperconjugative effect which stabilizes the positive charge. \(CH _3^{+}\) methyl carbonium ion does not have both of these effects, therefore it is the least stable. Therefore \(\begin{array}{*{20}{c}} {\,\,\,\,\,C{H_3}} \\ | \\ {\mathop {C{H_3} - C - C{H_3}}\limits_ + } \end{array}\) have maximum stability.

The most volatile compound is
1 \(2, 2-\) dimethyl propane
2 \(2-\) methyl butane
3 Isobutane
4 \(n-\) pentane
Explanation:
The boiling point is inversely proportional to the branch in the compound. Therefore, \(2,2\)-dimethyl propane has more branching, higher boiling point.
