`NCl_(3)` gets hydrolysed to from `NH_(3)andHOCl` while `PCl_(3)` on hydrolysis gives `H_(3)PO_(3)andHCl`. Explair why ?

Explanation

To explain why \( NCl_3 \) hydrolyzes to form \( NH_3 \) and \( HOCl \), while \( PCl_3 \) hydrolyzes to form \( H_3PO_3 \) and \( HCl \), we can analyze the differences in the bonding and electronegativity of nitrogen and phosphorus in relation to chlorine.

### Step-by-Step Solution:

1. **Understanding Hydrolysis of \( NCl_3 \)**:
- When \( NCl_3 \) (nitrogen trichloride) undergoes hydrolysis, it reacts with water.
- The reaction can be represented as:
\[
