Paragraph for Question 11 and 12
P & Q are isomers of dicarboxylic acid $\mathrm{C}_{4} \mathrm{H}_{4} \mathrm{O}_{4}$. Both decolourize $\mathrm{Br}_{2} / \mathrm{H}_{2} \mathrm{O}$, On heating P forms the cyclic anhydride. Upon treatment with dilute alkaline $\mathrm{KMnO}_{4}$, P as well as Q could produce one or more than one from S, T and U. [JEE 2013]
