Vedclass · Answer

(D) The formation of a stable hydrate from an aldehyde or ketone depends on the presence of strong electron-withdrawing groups attached to the carbonyl carbon. $1$. $CCl_3-CHO$ (Chloral) forms a stable hydrate called chloral hydrate due to the strong $-I$ effect of the three chlorine atoms. $2$. Ninhydrin forms a stable hydrate because the carbonyl group is highly electrophilic due to the presence of adjacent electron-withdrawing carbonyl groups. $3$. $(CF_3)_2CO$ (Hexafluoroacetone) forms a stable hydrate due to the strong $-I$ effect of the two $-CF_3$ groups. Therefore,all of these compounds form stable hydrates.
