(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)
