I want to ask that.. in case of H2O is it sp3d2 then 3d(red underlined) is empty...?

and in case of CN d2sp3 then( blue overlined) is empty? also in case of CN the 2 electrons in 3d doesnot get paired???

For H2O sp3d2
and CN d2sp3

but i am not confirmed about the reasons.

okay thanx....kabhie aisa q kiya nahin...

so both d2sp3...

But in fitj package me H20 wala sp3d2 diya hai... (widout any reason)[7]

and in every book they never give this type of examples, only give one in which d4 or d5 se jada wala..

I also din't find anywhere

But this is what I think

for octahedral complex this is the energy level diagram

If the above two are empty (with pairing or without paring in t2g) then hybridization is d2sp3

haan yahi sahi lag raha hai..

d2sp3
