Markovnikoff's Rule

Question 1

When is Markovnikoff’s rule used?

Answer 1

When there are unsymmetrical reactants in a reaction that produces a major and minor product

Question 2

What does Markovnikoff’s rule state?

Answer 2

The major product is the product where the hydrogen of a reactant attaches itself to the carbon with the highest number of pre-existing hydrogens. The minor product is the product where the hydrogen of a reactant attaches itself to the carbon with the lowest number of pre-existing hydrogens.

Question 3

When is there no major or minor product with Markovnikoff’s rule?

Answer 3

When there is a 50/50 split and all available spaces have equal numbers of pre-existing hydrogens

Question 4

What is the only type of reaction Markovnikoff’s rule is used in?

Answer 4

Addition reactions

Question 5

What does anti-Markovnikoff’s rule state?

Answer 5

The major product will be the one where the hydrogen removed in the reaction comes from the carbon with the least number of hydrogens attached to it

Question 6

What is the only type of reaction anti-Markovnikoff’s rule is used in?

Answer 6

Elimination reactions
