Answer 1

There's no anti markovnikov addition here so intermediate isva carbocation on middle carbon atom of propene.

Answer 2

Peroxide effect is only observed in case of HBr/H2O2.The intermediate during the addition of HCl to propene in presence of peroxide is carbocation where the positive charge is over the middle carbon of propene. Here we will get merconikov's product that is CH3CHBrCH3. This is simple addition reaction of olifin. In presence of HBr/H2O2 we will get anti merconikov's product as major product.
