Alkyne Reactions Tautomerization - Crash Course Organic Chemistry
Carbon-carbon double bonds are pretty common in nature, but triple bonds between carbons, called alkynes, are not. When alkynes do pop up in nature, it’s usually in a compound that’s toxic to humans, however, we can synthesize alkynes...

Bond Length and Bond Energy
In this video Paul Andersen explains how the bond length and bond energy are calculated using an energy distance graph. The strength of the bond is determined by the charges in the constituent atoms. As the charge increases the bond...

The Chemistry of Arynes (Benzyne)
In this course we've come across some surprising structures, but benzyne is one of the most surprising. It would seem impossible that a triple bond could form on a benzene ring, and in truth it can't fully form, but benzyne is a molecule...
