Current Question (ID: 10905)

Question:

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

Options:

1. $(CH_3)_3C^+CHCH_3$
2. $CH_3CH_2CH^+CH_2CH_3$
3. $(CH_3)_2CCH_2CH_2CH_3^+$ (Correct)
4. $CH_3CH_2CH_2CH_2^+$

Solution:

$\text{Hint: Stability of carbocation is explained by hyperconjugation.}\n\n\text{Explanation:}\n\n\text{As the number of alpha hydrogen increases, the hyperconjugation structures are increases and the stability of carbocation also increases.}\n\n\text{The structures are as follows:}\n\n\text{Option 1: 3 alpha hydrogens}\n\text{Option 2: 4 alpha hydrogens}\n\text{Option 3: 8 alpha hydrogens}\n\text{Option 4: Least substituted primary carbocation, least stable}\n\n\text{Greater the number of hyperconjugation structures, more is the stability of the carbocation.}\n\n\text{Hence, option 3 is the correct answer.}$
