Consider the following reaction sequence:

The product 'B' is:

(A)(see structure)
(B)(see structure)
✓ Correct
(C)(see structure)
(D)(see structure)

Answer: (B)

Solution

The reaction involves reduction of a nitro group to an amino group, followed by diazotization and coupling. The nitro group on the benzene ring is reduced to an amino group. Upon diazotization and subsequent reaction, the diazonium group can be replaced or undergo coupling. The product B is 4-aminocinnamaldehyde, where the amino group is retained and an aldehyde group is present on the side chain.
