उत्तर

Degenerate orbitals are the orbitals of the same subshell of the same main shell.

Hence, these are (3dxy, 3d z2, 3dyz) and (4dxy, 4dxz, 4d z2).

The arrangement of orbitals on the basis of energy is based upon their (n + l) value. Lower the value of (n + l), lower is the energy. For orbitals having same values of (n + l), the orbital with lower value of n will have lower energy.

Based upon the above information, arrange the following orbitals in the increasing order of energy.

1s, 2s, 3s, 2p
