Sweet smelling organic compound Is slowly oxidized by air in presence of light to a highly poisonous gas. On heating with silver powder, it forms a gaseous substance B, which is also produced by the action of calcium carbide on water. Identify A and B and write the chemical equations of the reactions involved.

An organic compound A (C_8H_6) reacts with dilute H_2SO_4 in presence of mercuric chloride to produce another compound (B) . B is also obtained when benzene reacts with an acid chloride in presence of anhyd. AlCl_3 . Identify A and B and give the reactions involved.

An organic compound A(C_2H_6O) reacts with sodium to form compound B and hydrogen gas. When heated with conc. H_2SO_4 at 413 K, A produces C(C_4H_(10)O) . C on reaction with conc. HI at 373 K forms D. C is also obtained when B is heated with D. Identify A, B, C and D and write chemical equations for the formation of B from A and the formation of C from B and D.
