Primary alkyl halide ` C_4 H_9 Br` (a) reacted with alcoholic `K O H` to give compound (b). Compound (b) is reacted with HBr to give (c) which is an isomer of (a). When (a) is reacted with sodtum metal it gives compound (d), `C_ 8 H_ 18` which, is different from the compound formed when n-butyl bromide is reacted with sodium. Give the structural formula of (a) and write the equations for all the reactions.
