CH3-CH2,CH = CH2 + HBr,peroxide =

(A) 2-Bromobutane
(B) 2, 2-Dibromobutane
(C) 1-Bromobutane
(D) 1, 2-Dibromobutane​

Answer 1

Answer:

option c

Explanation:

kharash effect

Answer 2

The IUPAC name of major organic product of the given reaction is (C) 1-Bromobutane.

- The given reaction proceeds according to anti-markovnikov's rule (which is also known as kharasch effect).

- It states that in the presence of peroxide, the hydrogen atom will attach to that carbon atom which contains lesser no of hydrogen atoms.

- Here, hydrogen goes to 2nd position and bromine adds up at 1 position.

CH3-CH2-CH=CH2 + HBr (Peroxide) ---> CH3-CH2-CH2-CH2Br

- The name of this compound is Bromobutane.
