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:

Answer:

Solution:

For single electron species energy only depends on ' n ' (principal quantum number)

So energy of $2 s = 2 p$
and energy of $3 d < 4 s$
