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