Question

Markovnikov rule explain it​

Answer 1

Answer:

Markonikoff's rule: When an unsymmetrical reagent is added to an unsymmetrical alkene, the negative part of the reagent is attached to the unsaturated C atom having less number of hydrogen atoms.

Thus, when HBr is added to propene, isopropyl bromide is obtained as major product.

Thus, bromide ion is added to middle carbon atom (having less number of H atoms) and proton is attached to terminal C atom.
