JEE AdvancedChemistryAldehydes Ketones and Carboxylic AcidsMCQ+3 / −1
P and Q are isomers of dicarboxylic acid C4H4O4C_4H_4O_4C4​H4​O4​. Both decolorise Br2Br_2Br2​/H2OH_2OH2​O. On heating, P forms the cyclic anhydride. Upon treatment with dilute alkaline KMnO4KMnO_4KMnO4​, P as well as Q could produce one or more than one from S, T and U. JEE Advanced 2013 Paper 2 Offline Chemistry - Aldehydes, Ketones and Carboxylic Acids Question 38 English ComprehensionCompounds formed from P and Q are, respectively,
