An alkyl halide `C_(5)H_(11)Br` (A) reacts with ethanolic `KOH` to give an alkene 'B' which reacts with `Br_(2)` to give a compound 'C' which on dehydrobromination gives an alkyne 'D'. On treatment with sodium metal in liquid ammonia one mole of 'D' give one mole of the sodium salt of 'D' and half a mole of hydrogen gas. Complete hydrogenation of 'D' yields a straight chain alkane. Identify A, B, C and D. Give the the reactions involved.
