Question
Markovnikov’s rule:
Alkenes undergo electrophilic addition reactions. They are triggered by the acid acting as an electrophile toward the π-electrons of the double bond.
Markovnikov’s rule states that when an unsymmetrically substituted alkene reacts with a hydrogen halide, the hydrogen atom adds to the carbon that has a greater number of hydrogens, e.g.,
Which given substrate is the most reactive toward Markovnikov’s addition?

Solution
The correct option is B
Presence of electron donating groups adjacent to the double bond increases the reactivity towards markonikov's addition.
Hence, (b) is the most reactive
