How to pronounce“Markovnikov”in English

Markovnikov’s rule can help us predict products of addition reactions involving alkenes Carbocations are stabilized by the inductive effect and hyperconjugation

This pattern is called Markovnikov’s rule: in these reactions, the proton will add to the side of the double bond that has the most hydrogens.

Almost too simple… So let's try another example and use Markovnikov’s rule again to predict the product.

With practice, we can use Markovnikov’s rule to help us predict lots of products.

If the alkyne is a terminal alkyne, this addition will follow Markovnikov’s Rule.
