36. Why is the bond angle in PH3 moleculelesser than that in NH3 molecule?(412008)

Answer»

Thebondpair inNH3is close to N in N-Hbond thanthebondpair in P-HbondinPH3. This is because the size of the nitrogen is smallthanphosphorus . As a result , the force of repulsion between the bonded pair of electrons inPH3is morethaninNH3. Therefore thebond angle in PH3molecule lesserthaninNH3.
