Correct Option: (4)
In the given sequence: - , which is a strong oxidizer used to oxidize alcohols to aldehydes or carboxylic acids. Thus, is oxidized to (benzoic acid).
- indicates a decarboxylation reaction, where the carboxyl group is removed, leading to the formation of a hydrocarbon, (toluene). Thus, the correct sequence is:

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).
