Write IUPAC names of the products obtained by addition reactions of HB

1.	Write IUPAC names of the products obtained by addition reactions of HBr to but-l-ene: (i) in the absence of peroxide and (ii) in the presence of peroxide.
Answer» Solution :(i) In absence of PEROXIDE, the product FORMED is according to Markovnikov rule. `CH_(3)-CH_(2)-CH-=CH_(2)+HBroverset("no peroxide")toCH_(3)-CH_(2)-CHBr-CH_(3)` (ii) In presence of peroxide, the product formed is according to antiMarkovnikov rule. `CH_(3)-CH_(2)-CH=CH_(2)+HBroverset("peroxide")toCH_(3)-CH_(2)-CH_(2)Br`
