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.

This can be explained through bond angle. As you already know that first one is Tetrahedral geometry arround central atom while 2nd one is Octahedral. So moving from tetrahedral to Octahedral we move from 109 bond angle to 90 bond angle. so as bond angle decreases distance between two groups also decreases therefore repulsion increases. But your statement is not a general statement because here CSFE not come in pictures so this statement is partially correct! Kindly accept my answer!
