Which of the following will react with water

Answer»

`CHCl_(3)`
`Cl_(2)C CHO`
`C Cl_(4)`
`ClCH_(2)CH_(2)Cl`

Solution :CHLORAL `(C Cl_(3)C HO)` readily reacts with `H_(2)O` to form chloral hydrate. This is due to the reason that the three ELECTRO withdrawing Cl ATOMS in `C Cl_(3)CHO` INCREASE the positive charge on the carbonyl carbon which holds the two OH groups firmly and thus favours the formation of stable hydrate.
