carbocation stability

Question

The order of stability of carbocations is:

RankGuru · Accepted Answer

The stability of carbocations ($R^+$) follows the order: **$3^\circ > 2^\circ > 1^\circ > 	ext{Methyl}$**.
- **Reasons**:
1. **Inductive Effect (+I)**: Alkyl groups are electron-donating. More alkyl groups around the positive carbon disperse the partial positive charge better.
2. **Hyperconjugation**: The number of $\alpha$-hydrogens increases in the order $1^\circ$ ($3$), $2^\circ$ ($6$), $3^\circ$ ($9$). More hyperconjugative structures lead to greater stability.
