Markovnikov’s 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. Alternatively, the rule can be stated that the hydrogen atom is added to the carbon with the greatest number of hydrogen atoms while the X component is added to the carbon with the least number of hydrogen atoms.
Both additions follow Markovnikov’s rule.
Here, in DCl, the chlorine gets attached to the less hydrogen containing substituents whereas the acid hydrogen (D) gets attached to the carbon with more hydrogen substituents. In this way, DI also gets attached to the compound.
