Question

Write the structure of A, B, and C in the following sequence of reactions:

\[\ce{CH3COOH ->[SOCl2]A ->[H2, Pd-BaSO4][]B ->[H2N-NH2][] C}\]

Answer 1

\[\ce{CH3COOH + SOCl2 ->\underset{(A)}{CH3COCl} + HCl + SO2}\]

\[\ce{CH3COCl + H2 ->[Pd-BaSO4][]\underset{(B)}{CH3CHO} + HCl}\]

\[\ce{CH3CHO + NH2{.}NH2 ->\underset{(C)}{CH3CH = N{.}NH2 + H2O}}\]
