MHT CET Chemistry question

Which of the following is TRUE for hydrolysis of tertiary halide?

(A)It is unimolecular as the overall reaction involves one molecule
(B)Rate determining step determines order of reactionCorrect
(C)Reaction involves two steps, because order of reaction is one
(D)Formation of - carbon is slowest stepCorrect

Answer: (B),(D)

Solution

Tertiary halide hydrolysis is SN1: the slow ionisation to the planar sp2 carbocation is the rate-determining step and its molecularity fixes the order (first order), so (b) and (d) are
