Question

Each compound below exhibits one lone pair. In each case, identify the type of atomic orbital in which the lone pair is contained.

Alright guys, let's take a look at this question, we have a six membered ring with all these double bonds and a negative charge here with two electrons. Notice that we have a lone pair adjacent to a PI bond, so we have a charge adjacent to a PI bond, so what do you think? can this lone pair resonate?Well, let's take a look, we can make a bond, break a bond and actually keep going around this molecule, we can have many resonance structures. Now, for this question, we're looking for what kind of orbital our lone pair is in, so what we're going to say is that if our lone pair is able to resonate it must occupy a p orbital. So, for that reason, we're going to say that our lone pair is in a p orbital. Alright guys, hopefully that makes sense, we need to actually determine if there's resonance structures possible and there's actually a few, okay? So I just went ahead and drew the arrows for the first one but remember that since we have a dot a ring that has alternating single and double bonds, we know that this structure this compound is going to be able to resonate a lot. Alright guys. So, just remember that if our lone pair can resonate once again it must occupy a p orbital which is the case in this question. Alright guys, so hopefully that made sense.
