Question

state and explain markownikoffs rule​

Answer 1

Explanation. The rule states that with the addition of a protic acid HX to an asymmetric alkene, the acid hydrogen (H) gets attached to the carbon with more hydrogen substituents, and the halide (X) group gets attached to the carbon with more alkyl substituents.

Answer 2

Markonikov, Russian chemist, after investigating several addition reactions, made a generalisation in 1869.

[According to this rule, the negative part of the addendum(adding molecule) adds to that carbon atom of the unsymmetrical alkene which is maximum substituted or which possesses lesser number of hydrogen atoms.]

So according to this rule, propene undergoes addition reaction forming 2-bromopropane in majority.
