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: A

Solution :

During the reaction carbocations are formed. \[3{}^\circ \]carbocation is more stable than \[1{}^\circ \]carbocation, hence the dehydration in \[3{}^\circ \] alcohol proceeds faster than \[1{}^\circ \]alcohol.
