In which of the following, orbitals are correctly arranged in the increasing order of their energies?

Options

  1. A4 f < 5 p < 5 d < 6 s
  2. B5 p < 4 f < 6 s < 5 d
  3. C5 p < 6 s < 4 f < 5 d
  4. D5 p < 5 d < 4 f < 6 s

Correct answer

C. 5 p < 6 s < 4 f < 5 d

Step-by-step solution

For multielectron atoms, the energy of the orbitals increases with an increase in their ( n +l) value. Thus, the order will be :- 5 p < 6 ~s < 4 f < 5 ~d
