Draw a resonance structure, complete with all formal charges and lone (unshared) electron pairs, that shows the resonance interaction of the acetyl with the ortho position in acetophenone.

Explanation:

find the solution below

The problem here is that according to aufbau principle before 3d orbital 4s subshell comes.after filling 3p orbital with electrons you have 4 electrons left, you place two in 4s with opposite spin and the other two in 3d in any of its two orbitals of total five orbitals with the same spin.

Bthats what im doing to and i figured it out it is b
