Solution and Explanation
(i) Benzene from benzoic acid:
\[
C_6H_5COOH + NaOH \xrightarrow{\Delta} C_6H_6 + Na_2CO_3
\]
(ii) Phthalimide from phthalic acid:
\[ C_6H_4(COOH)_2 \xrightarrow{NH_3, \Delta} C_6H_4(CO)NH \]
(iii) \( m \)-Nitrobenzaldehyde from benzaldehyde:
\[ C_6H_5CHO + HNO_3 \xrightarrow{Conc. H_2SO_4} C_6H_4(NO_2)CHO \]
