Question
$\left(\mathrm{CH}_3\right)_3 \mathrm{C}^{+}$ is more stable than $(\text{CH}_3)_2\stackrel{{+}}{\hbox{C}}\text{H}.$ Explain why.
✓

Answer

It is due to more +1 effect (positive inductive effect) of three alkyl groups which are electron releasing groups, make it more stable than $2^{\circ}$ carbocation which has two electron releasing alkyl groups. Secondly, $\left(\mathrm{CH}_3\right)_3 \mathrm{C}^{+}$ is most stable due to hyperconjugation.
