(a) `NCl_(3)` gets readily hydrolysed while `NF_(3)` does not. Why ?
(b) What kind of molecules show disproportionation reactions ? Give one example of a compound each of nitrogen and phosphorus which show disproportiionation reactions. Write chemical equation in each case.

Text Solution

Verified by Experts

(a) In `NCl_(3), Cl` has vacant d-orbitals to accept the lone pair of electrons donated by O-atom of `H_(2)O` molecule but in `NF_(3)`, F does not have d-orbitals. Thus, `NCl_(3)` undergoes hydrolysis but `NF_(3)` does not.
`NCl_(3) + 3 H_(2)O rarr NH_(3) + 3HOCl" ," " "NF_(3) + H_(2)O rarr No` reaction
(b) Compounds in which one of elements exists in three different oxidation states can show disproportionation reactions. For example,
`3 Hoverset(+3)(NO)_(2) rarr overset(+5)(HNO_(3)) + 2overset(+2)(NO)+H_(2)O" ,"" "4H_(3)overset(+3)(PO_(3))overset(Delta)rarr 3H_(3)overset(+5)(PO_(4)) + overset(-3)(PH_(3))`
