(A) NCl₃

Hybridisation of central atom does not change during hydrolysis but mechansim is followed by SN².

(B) At high temperature S_N1 mechanism takes place in NF₃ molecule.

(C) BCl₃
       Hybridisation of central atom in transition state changed.

(D) SF₄

Only proton donor acids are formed as final produced
