Question

complete the given reactions and compare the boiling points of their products?

Answer 1

Answer:

2 is the correct answer

Answer 2

we have to complete the given reactions and compare the boiling points of their products.

solution : when HBr is added to alkenes, alkyl halides forms as a product.

(i) CH3 - CH2 - CH = CH2 + HBr -- (peroxide) --> CH3-CH2-CH2-CH2-Br (product A)

(ii) CH3 - CH= CH - CH3 + HBr ---> CH3- CH2 - CH(Br) - CH2 - CH3 (product B)

(iii) CH3 - C(CH3)=CH2 + HBr ----> CH3-(Br)C(CH3)-CH3 ( product C)

we know, The boiling points of Halo alkanes decreases with increasing branches.

order of products in term of branches ...

C > B > A

so order of boiling point of products ..

A > B > C

Therefore the correct option is (1)
