Which of the following is/are not correct with respect to energy of atomic orbitals of hydrogen atom? (A) 1 ~s 2 p 3 ~d 4 ~s (B) 1 ~s 2 ~s =2 p 3 ~s =3 p (C) 1 ~s 2 ~s 2 p 3 ~s 3 p (D) 1 ~s 2 ~s 4 ~s 3 ~d Choose the correct answer from the options given below :

Options

  1. A(A) and (C) only
  2. B(B) and (D) only
  3. C(C) and (D) only
  4. D(A) and (B) only

Correct answer

C. (C) and (D) only

Step-by-step solution

For single electron species energy only depends on ' n ' (principal quantum number) So energy of 2 ~s =2 p and energy of 3 ~d < 4 ~s
