Carbonyl CompoundHard

Question

Compound A (molecular formula C2H8O) is treated with acidified potassium dichromate to form a product B (molecular formula C2H6O). B forms a shining silver mirror on warming with an aqueous solution of H2NCONHMH2 and sodium acetate gives a product C. Identify the structure of C.

Options

A.CH3CH2CH = N.NHCOH2
B.
C.
D.CH3CH2CH = N.CONHNH2

Solution

A is p-alcohol because its oxidation gives an aldehyde ′B′. B gives shining mirror with ammonical silver nitrate (Tollen′s reagent)
Thus structure of compound A is CH3Ch2CH2OH(M.F. = C3H8O)
