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.

An organic compound (a) reacts with sodium metal and forms (b) . On heating with conc. H_(2)S0_(4) (a) gives diethyl ether. (a) and (b) are respectively

An organic compound 'A' (C_2H_6O) reacts with sodium to form a compound 'B' with the evolution of hydrogen gas and gives a yellow compound 'C' when treated with iodine and NaOH. When heated with conc. H_2SO_4 at 140^@C it gives a compound 'D' C_4H_(10) which on treatment with HI at 100^@C gives 'E'. 'B' when heated with 'E' also gives back 'D'. Identify 'A' to 'E' and write equations for the reaction involved.
