EEJ MAIN Chemistry QUESTION #7198
Question 1
Identify the most stable carbocation among the following species.
  • $(CH_{3})_{3}C^{+}$✔️
  • $CH_{3}CH_{2}^{+}$
  • $CH_{3}^{+}$
  • $(CH_{3})_{2}CH^{+}$
Correct Answer Explanation

The stability of carbocations follows the order: $3^{\circ} > 2^{\circ} > 1^{\circ} > \text{methyl}$.

  • $(CH_{3})_{3}C^{+}$ is a tertiary ($3^{\circ}$) carbocation. It is the most stable due to the maximum inductive effect (+I) and hyperconjugation from the nine $\alpha$-hydrogens[cite: 3, 49].
