Detailed explanation-1: -Tert-butylbromide undergoes substitution by SN1 mechanism because it is able to form a stable carbocation in the first step after cleavage of the halide group. The carbocation then reacts with the nucleophile OH-.
Detailed explanation-2: -SN1 and SN2 are two of the most common reactions involved in organic chemistry. SN1 is a substitution reaction which often occurs with carbonyl compounds as well as benzene, while SN2 is another type of nucleophilic substitution reaction that more commonly occurs with alkyl halides and also benzoins.
Detailed explanation-3: -SN1 reaction mechanism follows a step-by-step process wherein first, the carbocation is formed from the removal of the leaving group. Then the carbocation is attacked by the nucleophile. Finally, the deprotonation of the protonated nucleophile takes place to give the required product.
Detailed explanation-4: -Example of SN1 Reaction NaOH solution hydrolyzes tert-butyl bromide, an example of an SN1 reaction. The pace of the reaction relies on the concentration of tert-butyl bromide, but the concentration of NaOH does not affect it. As a result, just tert-butyl bromide is required to determine the rate.
