What is the definition of Markovnikov rule?

• The Markovnikov rule states that in addition reactions to unsymmetrical alkenes, the hydrogen atom is added to the carbon atom that has the lesser number of hydrogen atoms already bonded to it.

• The Markovnikov rule states that in addition reactions to unsymmetrical alkenes, the hydrogen atom is added to the carbon atom randomly.

• The Markovnikov rule states that in addition reactions to unsymmetrical alkenes, the hydrogen atom is added to the carbon atom that has the same number of hydrogen atoms already bonded to it.

• The Markovnikov rule states that in addition reactions to unsymmetrical alkenes, the hydrogen atom is added to the carbon atom that has the greater number of hydrogen atoms already bonded to it.
