Although `PF_5, PCl_5` and `PBr_5` are known, the pentahalides of nitrogen have not been observed.
Phosphorous has lower electronegativity than nitrogen.

Text Solution

Verified by Experts

Nitrogen is smaller in size and hence has higher electron density than phosphorous, so there are additional repulsions to the incoming electron.

PCl_(5) is an example of a molecule having sp^(3)d -hybridisation. Three out of the orbitals in sp_(x)p_(y) -hybridisation while remaining two have p_(x)d_(x^(2)) -hybridisation. If P-atom is attached to substitutuents differ in electronegativity, as in PCl_(x)F_(5-x) , then it is has been experimently observed that the more electronegativity substituent occupies the axial position of t.b.p geometry.
