Re: Staying Motivated

I’m very reward oriented, so to motivate yourself to watch the lectures or do homework I recommend giving yourself little gifts when you complete the tasks! For example if you watch a couple of lectures and do the work problems, then you get to order a pizza or do a facemask or something you enjoy.

Re: sapling #15

I remember it as every bond has at least one sigma bond, and then the rest are pi bonds so:
Single bond = 1 sigma bond
Double bond= 1 sigma bond + 1 pi bond
Triple bond= 1 sigma bond + 1 pi bond + 1 pi bond

Hope that helps!

It’s kind of confusing, I don’t know if I ...

Hi, I believe it means that the pi bond can move around to the other bonds because of resonance, so it is not permanently in the one location, therefore delocalized.
