Ans 28 : A) The rate remains the same
The reactant tert-butyl bromide is a tertairy halide so it will undergo a SN1 mechanism. SN1 mechanism occurs in two steps and the rate of reaction depends only on the reactant and not on nucleophile.
So increasing the concentration of ethanol , will not affect the rate of reaction.

The mechanism of these acid catalyzed substitution reactions are labeled as Syl (substitution, nucleophilic, unimolecular) and S2 (substitution, nucleophilic, bimolecular). Tertiary alcohols follow the Snl route, primary alcohols follow the S2 route, and secondary alcohols can follow either path. Under acidic conditions, the mechanism (Figure 1) of the Sul reaction involves rapid protonation of the alcohol, followed by the...
