Consider the following reaction sequence.
the correct option(s) is(are)
Options:(select one or more)
Answer:
A, B
Solution:
Starting compound (nitrotoluene) on reduction with reagents like Sn/HCl or H₂/Pd (P) forms aniline derivative (Q).
Treatment with NaNO₂/HCl (R) converts it into a diazonium salt (S).
On hydrolysis (H₂O), diazonium salt gives phenol (T). Strong oxidation (U, KMnO₄/KOH, heat) converts the –CH₃ group into –COOH, forming benzoic acid. Hence the correct sequence matches option (A & B).
