Question

Carbocation which is most stable is:

• A.
  $$C{H}_{3}C{H}_2^{+}$$
• B.
  $$C{H}_3^{+}$$
• C.
  $$C_6{H}_{5}C{H}_2^{+}$$
• D.
  $$C{H}_{3}C{H}_{2}C{H}_2^{+}$$

Answer 1

The correct option is C

$$C_6{H}_{5}C{H}_2^{+}$$
Carbocation stability depends upon inductive effect, hyperconjugation, resonance among which resonance is dominating effect. Among the four given options, benzyl carbocation is the most stable because it is the only one which is resonance stabilised. Hence, the correct answer is option (c).
