Hydrolysis of `NCl_(3)` gives `NH_(3)` and X. which of the following is X?

Hyarolysis of NCl_3 gives NH_3 and X . Which of the following is X ?

Statement -1 : Hydrolysis of NCl_(3) gives NH_(4)OH and HOCl while PCl_(3) on hydrolysis gives H_(3)PO_(3) and HCl. Statement -2 : The difference is due to the change in polarity of P^(+sigma)-CI^(-sigma) bond in PCl_(3) in contrast to N^(-sigma)-CI^(+sigma) bond in NCl_(3) .

Statement -1 : Hydrogen of NCl_(3) gives NH_(4)OH and HOCl while PCl_(3) on hydrolysis gives H_(3)PO_(3) and HCl. Statement -2 : The difference is due to the change in polarity of P^(+sigma)-CI^(-sigma) bond in PCI_(3) in contrast to N^(-sigma)-CI^(+sigma) bond in NCI_(3) .

On hydrolysis, NCl_(3) gives NH_3 and HOCl while PCl_3 gives H_3PO_3 and HCl - explain.
