Solution:
- PLAN eactant is cyclic anhydride and chan es to dicarboxylic acid on hydrolysis.
Also there is decarboxylation on heating if there is keto group w.r.t $-\mathrm{COOH}$ group. Ozonolysis cleaves $(\mathrm{C}=\mathrm{C})$ bond and $\mathrm{H}{2} \mathrm{O}{2}$ oxidises - $\mathrm{CHO}$ to $-\mathrm{COOH}$ group.
Anhydride
Thus, number of $-\mathrm{COOH}$ groups in $P=2$.
