Question

Relative stability of the following carbocations i) $\mathrm{CH}_{3}^{+}$ii) $\mathrm{CH}_{3} \mathrm{CH}_{2}^{+}$iii) $\left(\mathrm{CH}_{3}ight)_{2} \mathrm{CH}^{+}$iv) $\left(\mathrm{CH}_{3}ight)_{3} \mathrm{C}^{+}$follows the decreasing order\

Professor PC Thomas Classes · Answer

Carbocation stability: $3^{\circ}>2^{\circ}>1^{\circ}>\mathrm{Me}^{+}$. The electropositive ( +I) alkyl groups cause a reduction of positive charge on the central carbon.
