Chloral hydrate is a gem-diol but still stable. How will you account for it ?

Explanation

In chloral hydrate, the presence of three Cl atoms with -I effect increases the magnitude of the positive charge on the carbonyl carbon atom. As a result , even a weak nuleophite like `H_(2)O` attackesto form a hydrate. Moreover, there is weak intermolecular hydrogen bonding inthe chloral hydrate which tends to increase it stability.
