Current Question (ID: 10933)

Question:

$\text{The most stable carbocation among the following is:}$

Options:

1. $\text{Triphenyl carbocation (three benzene rings attached to C}^+\text{)}$ (Correct)
2. $\text{Diphenylmethyl carbocation (two benzene rings and one CH}_3 \text{ attached to C}^+\text{)}$
3. $\text{Phenylethyl carbocation (one benzene ring and one C}_2\text{H}_5 \text{ attached to C}^+\text{)}$
4. $\text{Tertiary carbocation with two CH}_3 \text{ and one C}_2\text{H}_5 \text{ groups}$

Solution:

$\text{Hint: The order of stability of carbocation is 3° > 2° > 1°}$ $\text{All carbocation given in options is tertiary or 3° carbocation. The most stable carbocation is the triphenyl carbenium ion. The triphenyl carbenium carbocation is stabilized by the resonance effect of three benzene rings.}$ $\text{Hence, option one is the correct answer.}$
