Write IUPAC names of the products obtained by addition reactions of HBr to hex-1-ene:
(i) in the absence of peroxide and
(ii) in the presence of peroxide.

Solution

(i) In the absence of peroxide. Hexene reacts with HBr in the absence of organic peroxide to form 2-Bromohexane. Addition takes place according to Markownikoffs rule.
CH subscript 2 space equals space CH space minus space stack CH subscript 2 space minus space CH subscript 2 with Hex minus 1 minus ene below space minus space CH subscript 2 space minus space CH subscript 3 space plus space straight H minus space Br

(ii) In the presence of peroxide. Hex-1-ene reacts with HBr in the presence of peroxide to form 1-bromohexane.
stack CH subscript 2 space equals space CH with Hex minus 1 minus ene below space minus space CH subscript 2 space minus space CH subscript 2 space minus space CH subscript 2 space minus space CH subscript 3 space plus space straight H space minus space Br
