Huckel’s Rule for Aromaticity + Time-saving Shortcut

Huckel’s rule is the most confusing and most tedious step in figuring out if a molecule is aromatic or antiaromatic. This video shows you how to calculate Huckel’s rule to ensure you ‘get’ the math, followed by a time-saving shortcut so that you DON’T actually have to DO the math every time.

In this video:
[0:15]Aromaticity review
[1:39] Using Huckel’s formula
[6:19] Determine antiaromatic/aromatic molecules
[7:36] Finding the pattern using electron pairs

Note: At 4:08, I state that cyclooctatetraene appears to be planar. Even though it might appear that way, the molecule actually takes a non-planar tub shape. This fact disqualifies it from following the conditions for aromaticity. Cyclooctatetraene is a non-aromatic compound.

You are the first chemistry teacher who actually made me understand what is exactly happening in a very simple way. Much love to you!

studying for the MCAT right now and your vids are saving me!! amazing explanations and your voice is super calming lol

[hijabicooks]

Never understood chemistry always avoided taking a subject that included chemistry but because i'm studying pharmacy I have to do it and thanks to you im actually enjoying it. Thank you

Thank You! After an hour in lecture + an office hours visit with my professor I was still lost. You helped me get this concept in just 10 minutes.

I did not see the short cut before. Thanks for showing, a light bulb has gone off and I now understand the pattern. Thanks Leah.

I love you soooo muchhhh Leah ~ Some other websites they'd just drop down the name huckel's rule and don't even try to explain as concisely as possible. Thanks again for the wonderful content!
