Vedclass · Answer

(D) The starting material is ninhydrin ($1,2,3$-indantrione). When it reacts with water $(H_2O)$,the central carbonyl group,which is highly electrophilic due to the electron-withdrawing effect of the two adjacent carbonyl groups,undergoes nucleophilic addition by water to form a gem-diol. This gem-diol is stabilized by intramolecular hydrogen bonding between the hydroxyl groups and the adjacent carbonyl oxygen atoms. The product is $2,2$-dihydroxy-$1,3$-indanedione.

The major product '$A$' formed in the above reaction is:
