Question

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.

Answer 1

Answer: (A)

Tertiary carbocation is more stable than primary carbocation

Answer 2

During the reaction carbocation are formed $3º$ carbocation is more stable than $1º$ hence the dehydration in $3º$ alcohol proceeds faster than $1º$ alcohol.
