Solution:
$$ \begin{array}{ll} \hline \text { Column I } & \text { Column II } \end{array} $$
A.
Undergo nucleophilic substitution of $Br^{-}$. Undergo elimination of $HBr$. Does not undergo nucleophilic addition. Does not esterify with acetic anhydride, can be dehydrogenated.
B.
Undergo nucleophilic substitution with $SOCl _2, PCl _5$ etc.
Does not undergo elimination. Does not undergo nucleophilic addition.
Undergo esterification with acetic anhydride.
Undergo dehydrogenation to give $C _6 H _5 CHO$.
C.
Does not undergo nucleophilic substitution, there is no leaving group.
Does not undergo elimination. Undergo nucleophilic addition at carbonyl carbon of $-CHO$.
Undergo esterification with acetic anhydride.
Does not undergo dehydrogenation.
D
Undergo aromatic nucleophilic substitution $\left(S _N Ar\right)$
Does not undergo elimination, nucleophilic addition, esterification or dehydrogenation.
