Sometimes, when maximum covalency is obtained, the halides become inert to water. Thus,

S F_{6}

is stable. This is because

S F_{6}

is coordinately saturated and sterically hindered. Thus,

S F_{6}

is inert to water, because of kinetic rather than thermodynamic factor.

CC l_{4}

cannot undergo hydrolysis as carbon does not have vacant d-orbitals to extend its covalency.

Rest other

PC l_{5}, S i C l_{4}

and

BC l_{3}

can undergo hydrolysis as follows

PC l_{5} + 4 H_{2} O \to H_{3} P O_{4} + 5 H^{+} C l^{-}

S i C l_{4} + 4 H_{2} O \to S i (O H)_{4} + 4 H^{+} C l^{-}

BC l_{3} + 3 H_{2} O \to B (O H)_{3} + 3 H^{+} C l^{-}
