Type: MCQ-conceptual-Medium-Class 12
Acid catalysed dehydration of t-butanol is faster than that of n-butanol because
A
tertiary carbocation is more stable than primary carbocation
B
primary carbocation is more stable than tertiary carbocation
C
t-butanol has a higher boiling point
D
rearrangement takes place during dehydration of t-butanol.
Correct Answer
Option A
Detailed Explanation
The dehydration of t-butanol proceeds faster because the tertiary carbocation formed is more stable than the primary carbocation that would form from n-butanol. Stability of the carbocation is a key factor in the rate of dehydration.
