- \(\text{CH}_3\text{CH(CH}_3)\text{CH}_2\text{OH}\)
- \((\text{CH}_3)_3\text{COH}\)
- \(\text{CH}_2=\text{CHCH}_2\text{CH}_2\text{OH}\)
- \(\text{CH}_3\text{CHOHCH}_2\text{CH}_3\)
Show Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Step 1: Carbocation stability order:
\[ 3^\circ > 2^\circ > 1^\circ \]
Step 2: tert-Butyl alcohol forms a tertiary carbocation.
\[ 3^\circ > 2^\circ > 1^\circ \]
Step 2: tert-Butyl alcohol forms a tertiary carbocation.
