JEE Main Chemistry question

tert-Butyl chloride reacts with OH⁻ by the SN1 mechanism, and rate ∝ [tert-butyl chloride]. One reason for this is that

(A)Stereochemical inversion takes place
(B)The tert-butyl carbocation is first formed, which is relatively stable, making ionization the (unimolecular) rate-determining stepCorrect
(C)The product tert-butyl alcohol is more stable
(D)The intermediate tert-butyl carbocation is stabilized by solvation

Answer: (B)

Solution

In SN1, the slow, rate-determining step is the unimolecular ionization of the substrate to form the carbocation; because the tertiary carbocation
