Vedclass · Answer

(D) Carbonyl compounds react with water to form gem-diols (hydrates). Usually,these are unstable and revert to the carbonyl compound. However,strong electron-withdrawing groups like $-CF_3$ or $-CCl_3$ stabilize the hydrate by increasing the electrophilicity of the carbonyl carbon through inductive effects. $CF_3-CO-CF_3$,$CF_3-CHO$,and $CCl_3-CHO$ form stable hydrates. Ninhydrin also forms a stable hydrate due to the presence of adjacent electron-withdrawing carbonyl groups. Benzaldehyde $(Ph-CHO)$ does not have such stabilizing groups,and its hydrate is unstable.

Which of the following does not give a stable product with water?
