Why is an s orbital needed for hybridisation? Why can’t I just have p2d or p3d or pd3 hybridisation?
S has the lowest energy state. So, electrons will go there first.
See but explanation of sp3 hybridisation comes from the fact that we are taking one electron from s and putting it into the p orbital right?
Atomic orbitals combine to form new one's, that leads to hybrid orbitals. I don't know about the lectron thing.
Okay I will try to send you the source of my Doubt. There’s one part in my class 11 notes where this doubt came from all of a sudden.
