Under what conditions, 2-methylpropene can be converted into isobutyl bromide (1-bromo-2-methylpropane) by hydrogen bromide ? Write the correct reaction involved.

Under what conditions can 2-methylpropene be converted into iso butyl bromide on reacting with HBr?

The alkyl halide C_4 H_9 Br (A) reacts with alcoholic KOH and gives an alkene (B) which reacts with bromine to give a dibromide (C). (C) is transformed with sodamide into a gas (D) which forms a precipitate when passed through ammoniacal silver nitrate solution. Give the structural formulae of the compounds (A), (B), (C) and (D) and explain the reactions involved.
