Question

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

(A) (A) and (C) only
(B) (C) and (D) only
(C) (B) and (D) only
(D) (A) and (B) only

Correct answer: B. In hydrogen atom E = –13.6 × 2 n z So energy only depends on orbit number(n) so 1s < 2s = 2p < 3s = 3p = 3d
