Identify degenerate orbitals from following for hydrogen atom.

Options

  1. A1 ~s and 2 ~s
  2. B1 ~s and 2 p
  3. C2 ~s and 2 p
  4. D3 ~s and 2 p

Correct answer

C. 2 ~s and 2 p

Step-by-step solution

An increasing order of energies of orbitals in the hydrogen atom is given by: 1 ~s < 2 ~s =2 p < 3 ~s =3 p =3 ~d < Thus, in hydrogen atom 2 ~s and 2 p are degenerate orbitals.
