Sulphur forms hexahalides tetrahalides dihalides and monohalids Sulphur forms only exafluoride but not hexacholorides. Hexabromides and hexaiodes Sulphur halids tend to hydorlyse easily sulphur hexaflouride is an exception of the oxohalids the most important are those of sulphur especially sulphur dichloride oxide (Thoiny chloride) SO_(2)Cl_(2) and sulphur dichloride dioxide (sulphuryl chloride) SO_(2)Cl_(2) these also hydrolyse in water. SF_(6) do not hydrolyse in water because

Answer»

Due to STRONG S-F bonds which cannot be BROKEN easily
Because of STERIC hinderance of six flourine atoms surroundin sulphur `H_(2)O` MOLECULES cannot approach sulphur
Due to double bond character of `S-F` bonds because of back bonding from flourine to sulphur
All the above
