Overall it is a $3$-step reaction where the $2^{nd}$ step is the rate-determining step.

Vedclass · Answer

(C) The acid-catalysed dehydration of $tert$-butyl alcohol follows an $E1$ mechanism.Step $1$: Protonation of the hydroxyl group to form an alkyloxonium ion. This is a fast and reversible step.Step $2$: Loss of a water molecule to form a $tert$-butyl carbocation. This is the slow and rate-determining step.Step $3$: Loss of a proton from the carbocation to form $2$-methylpropene (isobutylene). This is a fast step.Since the carbocation formed is symmetric,only one alkene ($2$-methylpropene) is obtained.Therefore,the correct statement is that it is a $3$-step reaction where the $2^{nd}$ step is the rate-determining step.
