Question

PH3 has the same geometry as NH3, however, the bond angle in PH3 is
less than that in NH3. Provide an explanation for this observation.

Accepted Answer

THE BOND ANGLE IN NH3​ IS LARGER THAN, IN PH3​ BECAUSE
THE P−H BONDS ARE LONGER AND THE LOWER ELECTRONEGATIVITY OF P
PERMITS ELECTRON-DENSITY TO BE DISPLACED TOWARDS HYDROGEN TO A GREATER
EXTENT THAN IN THE CASE OF NH3.

Expert's answer

The bond angle in NH3 is larger than, in PH3 because the P−H bonds are longer and the lower electronegativity of P permits electron-density to be displaced towards hydrogen to a greater extent than in the case of NH3.
