a) & b)
c) The given spectrum shows peaks corresponding to the Hydrate as it is the predominant species in an aqueous solution of Phenyl-glyoxal.
The stability of diol is due to the ease of hydrogen bonding that is formed between Carbonyl C=O and any one of the 2 -OH of diol.
As in aqueous solution, the predominant species is hydrate form, IR absorptions corresponding to hydrate form are appeared & not the diketone (Ketonic + Aldehydic).
d) The hydration at aldehydic C=O but not the ketonic C=O occurred.
i) From the mechanism of hydration of Carbonyl functionality, in both acidic & basic medium shows that there is a nucleophilic addition to Carbonyl Carbon.
(1)Phenylglyoxal. Phenylglyoxal is in equilibrium with its hydrate as shown: H + H2O HO OH (a)...
