MCQ
The most stable carbonium ion among the following is
  • ${C_6}{H_5}\mathop C\limits^ + H{C_6}{H_5}$
  • B
    ${C_6}{H_5}\mathop C\limits^ + {H_2}$
  • C
    $C{H_3}\mathop C\limits^ + {H_2}$
  • D
    ${C_6}{H_5}C{H_2}\mathop C\limits^ + {H_2}$

Answer

Correct option: A.
${C_6}{H_5}\mathop C\limits^ + H{C_6}{H_5}$
a
(a) ${C_6}{H_5}\mathop {CH}\limits^{ + \,\,\,\,} \,{C_6}{H_5}$ is the most stable carbonium ion due to resonance
