Markovnikov's rule

Markovnikov's rule states that, in chemical reactions found particulary in organic chemistry, when a a hydrogen halide[?] reacts with the carbon-carbon double bond[?] of an unsymmetrical alkene, giving an alkyl halide[?], the hydrogen adds to the carbon of the alkene functional group that has the greater number of hydrogen substituents[?], and the halogen adds to the carbon on the other end of the double bond which has a smaller number of hydrogen substituents.

The rule may be summed up by quoting that the rich get richer and the poor get poorer, in that a carbon rich in substituents will get more substituents and the carbon with more hydrogens attached will get the hydrogen in case of many different organic addition reactions[?].
