(i) In the absence of peroxide, the product formed is according to Markovnikov rule.
`CH_(3)-CH_(2)-CH=CH_(2)+HBroverset("No peroxide")rarrCH_(3)-CH_(2)-CHBr-CH_(3)`
(ii) In the presence of peroxide, the product formed is according to antiMarkovnikov rule.
`CH_(3)-CH_(2)-CH=CH_(2)+HBroverset("peroxide")rarrCH_(3)-CH_(2)-CH_(2)-CH_(2)Br`
