Neutralization Reaction
In a neutralization reaction (or acid-base reaction) a proton is transferred from the Brinsted--Lowry acid to the Brinsted--Lowry base. Water is amphoteric and so it can serve as either an acid or a base in a neutralization reaction. The...

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...
