Formation of Hydrates
MECHANISM FOR THE ACID CATALYSED FORMATION OF HYDRATES
An acid/base reaction. Since there is only a weak nucleophile we need to activate the carbonyl by protonating on O.
The nucleophilic O in the water attacks the electrophilic C in the C=O, breaking the π bond and giving the electrons to the positive O
An acid/base reaction. Deprotonation of the oxonium ion neutralises the charge giving the hydrate.
