Time management is very much important in IIT JAM. The eduncle test series for IIT JAM Mathematical Statistics helped me a lot in this portion. I am very thankful to the test series I bought from eduncle.

One is pyramidal inversion which is shown by Nitrogen SP3 . Other is berry pseudo rotation which is shown by many molecule one such molecule is PF5.
No all molecule can't show inversion as there is energy barrier which molecule has to cross.
Inversion of ammonia is rapid at room temperature. In contrast, phosphine (PH3) inverts very slowly at room temperature (energy barrier: 132 kJ/mol)
