In aqueous base, 97% of 2,2-diphenylethanal is present as a species different from the aldehyde, enol or aldol addition or condensation products. What is this species? Please also try to explain the mechanism.
The Attempt at a Solution
I'm confused in the first step. Would the hydroxyl ion attack carbonyl carbon or the diphenyl carbon; or it will attack on the enol form. please help.
