The energies of orbitals of hydrogen atom are in the order

The energies of orbitals of hydrogen atom are in the order
  1. 3s < 3p < 4s < 3d < 4p
  2. 3s < 3p < 3d < 4s < 4p
  3. 3s = 3p = 3d < 4s = 4p
  4. 3s = 3p = 3d < 4s < 4p

Solution

In hydrogen atom, the energy of electron depends upon principle quantum number only and not on azimuthal quantum number due to lack of inter electronic repulsions. ^
