Huckel's Rule: aromatic vs. antiaromatic (4)

Описание: Organic chemistry: How to use Huckel's Rule to determine whether a molecule is aromatic, antiaromatic, or nonaromatic.

These videos are offered on a "pay what you like" basis. You can pay for the use of the videos at my website:

For a list of all the available video series, arranged in suggested viewing order, go to my website.

These videos are designed to help students who are finding the material difficult, so I go very slowly, with lots of repetition and examples. If you don't find this material difficult, you might be very bored by these videos and might prefer to learn straight from a textbook.

Here is a playlist containing all the videos in this series:
   • Huckel's Rule: aromatic vs. antiaromatic (1)  

(1) The rule for determining hybridization
(2) The rule for determining hybridization, concluded
(3) The exception to the rule for determining hybridization
(4) What are the valence orbitals of hybridized atoms?
(5) "Flat", "cyclic", "completely conjugated"
(6) Counting pi electrons
(7) Counting pi electrons--harder problems
(8) Counting pi electrons--more problems
(9) Counting pi electrons--more problems
(10) Counting pi electrons--more problems
(11) Counting pi electrons--even more problems
(12) Counting pi electrons--rings with substituents
(13) Counting pi electrons--polycyclics
(14) Counting pi electrons--radicals; and a puzzle
(15) Counting pi electrons--triple bonds
(16) The lesson from triple bonds
(17) A deeper look: why do the rules work?
(18) A deeper look, continued
(19) A deeper look: Why is there an "exception to the rule" for hybridization?
(20) A deeper look: Why "flat"?
(21) A deeper look: Why "4n+2"? Molecular orbitals
(22) Why "4n+2"? Frost diagrams
(23) Why "4n+2"?
(24) Why "4n+2"?
(25) Why "4n+2"?
