Question

Bond angle in Nh3 is 107°,but in PH3 is 92° why?

Please answer it fastly guys please​

Answer 1

Answer:

Step-by-step explanation:

The main reason is there is no hybridisation in PH3 as the bond between H and P is not strong enough to cause excitation and make hybrid orbitals. As a result, the bond angle in PH3 is close to 90 while in NH3, it is about 107 as a consequence of hybridisation.
