Answer 2

Hello dear,

● Gerade orbitals -
- Orbitals which are left unchanged by the operation of inversion are called gerade orbitals.


● Ungerade orbitals -
- Orbitals which undergo a change in sign by the operation of inversion are called ungerade orbitals.


● Classification of orbitals -
We can classify given options into gerade & ungerade orbitals -
# Gerade orbitals => 1s, 2ps
# Ungerade orbitals => 3dxy

Hope this helps you...
