1.	An acid (A) which is an important constituent of vinegar, on reaction with red P_4 and Br_2 gives a monobromoderivative (B) which on reaction with NH_3 gives a white solid (C). However, ethanal on reaction with a mixture of ammonium chloride and sodium cyanide undergoes strecker synthes is to give a product which on acidic hydrolysis gives another high melting solid (D). The intermediate involves in the conversion of (A) and (B) is
