Problem
An organic compound (A) on heating produces two gases (B) and (C) and neutral oxide (D) which turns cobalt chloride paper pink. Gas (B) turns lime water milky and produces an acidic solution with water. Gas (C) produces a poisonous gas (E) with chlorine gas, this gas with ammonia gives an organic compound (F) which on further reaction with (D) gives NH3 gas. Then, compounds (A) and (F) can be found as:
(1) H2C2O4 and NH2CONH2
(2) CH3COOH and NH2CONH2
(3) CHCl3 and CH3CONH2
(4) CH3Cl and NH2COONH4
