Question

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

Select the correct option:

(B) and (D) only

(A) and (B) only

(A) and (C) only

✓ Correct! Well done.

✗ Incorrect. Try again or view the solution.

Solution

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