Expert Answer
Markovnikov's Rule:
In case of Markovnikov's rule, the addition of halogen halides to alkenes is an electrophilic addition reaction.
Since a 20 carbocation(I) is more stable than 10 carbocation(II), therefore carbocation(I) is predominantly formed.
Markovnikov's addition occurs through the more stable carbocation intermediate.
Peroxide effect :
Peroxide effect is observed only with HBr and not with HF,HCl, or HI
