The trihalide which forms oxocations on hydrolysis is

VA group elements form both trihalides and pentahalides of the tyep MX_(3) and MX_(5) respectively (M-VA group element, X-halogen). Both type of halides undergo hydrolysis. Most of these covalent in nature and process covalent bonds formed by overlapping of orbitals. Aqueous solution of these halides conduct electricity. The trihalide which undergoes partial hydrolysis is

ClF on hydrolysis forms

Identify: A nitrogen trihalide which does not undergo hydrolysis.

Trihalide which does not undergo hydrolysis easily is

_______form oxocations

_______form oxocations

_______form oxocations
