Q55B - Organic Chemistry (Mcmurry)

Question

Question: Arrange the carbocations below, in order of increasing stability:

b.

Step-by-Step Solution

Answer

Answer

Step 1: Stability of carbocation

Rules for the stability of carbocation:

1. More the resonance in the system more stable is the carbocation
2. More the hyperconjugation that is the number of hydrogen with respect to the carbocation more stable is the carbocation
3. More is the conjugation with the double bond in the molecule more stable is the carbocation

Step 2: Order for Stability of carbocation

On the basis 

Rule 1: More the resonance in the system more stable is the carbocation.

Rule2: More the hyperconjugation that is number of -hydrogen with respect to the carbocation more stable is the carbocation
