Answer Key / Explanation : (a) -

(a)

(2DU in A). It may have either two (C==C) or one (  bond. Formation of three compounds on oxidation of (A) shows that it contains two ( ) bonds. (B) reduces ammoniacal   solution and gives iodofrom test

Therefore, (B) is an aldehyde and it is (  (two-C- atom aldehyde)

(C) is acetone containing group (since it gives iodoform test)

(D) is two –C dibasic acid since it gives and  with conc. . So (D) may be oxalic acid ( ) (two C atoms). Total C atoms in (C) must be four (A)
