Question

Ch3-ch=ch2+hbr in presence of benzoyl peroxide give products

Which of the following is a possible products in above reaction

(1)ch3-ch2-ch2-br

(2)ch3-ch(br)-ch2-br

(3)ch3-ch(ch2br)-ch(ch2br)-ch3

(4)all of them

Answer 1

Answer:

Option (1) is correct.

Explanation:

Benzoyl peroxide is initiator. in presence of peroxide addition of hbr follows anti markonikoff rule.

hbr dissociates to give H(+) and br(-).

so, according to the anti markonikoff rule H(+) will goes to carbon having lesser number of hydrogen atoms and br(-) goes to carbon having more number of hydrogen atoms.

The reaction is as follows :

CH3-CH (double bond) CH2 --------CH3-CH2-CH2-br. so option (1) is correct.
