This is the same thing my professor was doin in class today, the difference is she just have the gift of explanation, even an unborn child can understand. Thank you my dear love. You are a God given gift.

Thank you! I'm sorry that your professor wasn't able to explain this (I had the same issues in undergrad). But I'm glad my videos can fill that gap for you

This was a mind boggling topic, I never thought I could understand it until you swooped in and saved the day. Thanks Leah for your great help!!

Absolute great teacher. Science can be fun and explained well besides reading the lines extracted from theories and lessons and this is what she proved. I will go over her videos more in the future and have subscribed to her. I wonder why would someone dislike such a legendary explaination.

Awesome!

My notes so I can understand this video: # of atomic pi orbitals equals the # of pi molecular orbitals. So if you have six pi electrons (from three pi bonds) that equals six pi molecular orbitals. This can be represented by a group of friends. Most stable is all of the friends getting along (completely bonding and low energy and happy), least stable is every single friend is not getting along with anyone (completely antibonding and high energy and unhappy). Nodes represent distance between two friends, increases energy and moves them to more antibonding level. And... I was just focusing on your great examples for the rest of the video. LUMO and HOMO make so much sense and the resonance example really helped with understanding the relative energies. Thanks. :) Now I feel ready for Diels-Alder stereochemistry and endo/exo stuff and how the pi orbitals overlap.
