Q. The stability of the carbocation decreases in the order
A) $R_{2}CH^{+} > R_{3}C^{+} > RCH_{2}^{+} > CH_{3}^{+}$
B) $R_{3}C^{+} > R_{2}CH^{+} > RCH_{2}^{+} > CH_{3}^{+}$
C) $CH_{3}^{+} > R_{2}CH^{+} > RCH_{2}^{+} > R_{3}C^{+}$
D) $CH_{3}^{+} > RCH_{2}^{+} > R_{2}CH^{+} > R_{3}C^{+}$
Explanation
(b)
Stability of alkyl carbocations can be explained by inductive effect and hyperconjugation. According to these two effect the stability order is
