A) \[{{C}_{6}}{{H}_{5}}\overset{+}{\mathop{C}}\,{{H}_{2}}\]
B) \[{{(C{{H}_{3}})}_{3}}\overset{+}{\mathop{C}}\,\]
C) \[\overset{+}{\mathop{{{C}_{2}}}}\,{{H}_{5}}\]
D) \[{{({{C}_{6}}{{H}_{5}})}_{3}}\overset{+}{\mathop{C}}\,\]
Correct Answer: D
Solution :
\[{{({{C}_{6}}{{H}_{5}})}_{3}}{{C}^{+}}\]is maximum stable. The three \[-{{C}_{6}}H_{5}^{-}\]groups attached to the carbonium ion stabilises it is due to resonance. The order of stability is\[{{({{C}_{6}}{{H}_{5}})}_{3}}\overset{+}{\mathop{C}}\,>{{(C{{H}_{3}})}_{3}}\overset{+}{\mathop{C}}\,>{{C}_{6}}{{H}_{5}}\overset{+}{\mathop{C}}\,{{H}_{2}}>{{\overset{+}{\mathop{C}}\,}_{2}}{{H}_{5}}\]You need to login to perform this action.
