An organic compound X is oxidised by using acidified K2Cr2O7. The product obtained reacts with phenyl hydrazine, but does not answer silver mirror test. The possible structure of X is
CH3COCH3
(CH3)2CHOH
CH3CHO
CH3CH2OH
The increasing order of the rate of HCN addition to compound A-D is
A. HCHO B. CH3COCH3
C.PhCOCH3 D. PhCOPh
A< B < C < D
D< B< C< A
D < C < B < A
C < D< B< A
If 'A' is C2H5NH2, 'B' is (C2H5)NH, 'C' is (C2H5)3N, then order of solubility in water is
A >B > C
B < A <C
C < B <A
C > B <A
