Solution:

$\left(\text{C}\right)_{7} \left(\text{H}\right)_{6} \left(\text{O}\right)_{2} \left(\text{P}\right) \underset{\left(2\right) \text{Δ}}{\overset{\left(1\right) \text{aq} . \left(\text{NH}\right)_{3}}{ \rightarrow }} \text{Q} \underset{\text{KOH}}{\overset{\left(\text{Br}\right)_{2}}{ \rightarrow }} \text{R}$

Here P is an acid, Q is amide and Q to R is Hoffmann's bromamide degradation as follows
