Official Solution
Correct Option:
(4)
2–Bromo–2–methylbutane is a tertiary alkyl halide. When it is treated with water (H O), it undergoes nucleophilic substitution (SN1 mechanism) to form the corresponding alcohol — 2–methyl–2–butanol. Water acts as the nucleophile and replaces the bromine atom with a hydroxyl group (–OH).
