Solution
The correct option is A Markovonikov's rule
The addition of hydrogen halides to unsymmetrical alkene takes place according to Markovonikov's rule.
When an unsymmetrical reagent adds to an unsymmetrical alkene, the negative part of the reagent gets attached to that unsaturated carbon atom which caries lesser number of hydrogen atoms.
The addition of hydrogen bromide to propene gives isopropyl bromide as a major product according to Markownikoff's rule.
CH3−CH=CH2+H−Br→CH3−CH(Br)−CH3
