NEET levelSingle correct optionDifficulty 1 of 3co003

Chloral ( $CCl X_{3} CHO$ ) forms a stable crystalline hydrate in water mainly because

Achloral has no carbonyl carbon
Bthe strong $- I$ effect of $CCl X_{3}$ makes the carbonyl carbon highly electrophilic and the gem-diol is stabilised by intramolecular hydrogen bonding
Cthe $CCl X_{3}$ group donates electrons by resonance to the carbonyl group
Dthe $+ I$ effect of $CCl X_{3}$ stabilises the gem-diol

Answer: B

Three chlorine atoms withdraw electrons, raising the electrophilicity of the carbonyl carbon and favouring hydration. Hydrogen bonding in

CCl X_{3} CH (OH) X_{2}

further stabilises the hydrate.
