Hydrocarbons Question 386

Question: Reaction of $ Br_2 $ on ethylene in presence of $ NaCl $ gives

Options:

A) $ BrCH_2-CH_2Br $

B) $ ClCH_2-CH_2Br $

C) Both A and B

D) None of these

Show Answer

Answer:

Correct Answer: C

Solution:

$ CH_2=CH_2+Br_2\xrightarrow{NaCl}\underset{\text{1,2}-dibromoethane}{\mathop{\underset{\underset{Br}{\mathop{|}}}{\mathop{CH_2}}-\underset{\underset{Br}{\mathop{|}}}{\mathop{CH_2}}}} $

$ \underset{1-bromo-2-chloroethane}{\mathop{+\underset{\underset{Cl}{\mathop{|}}}{\overset{2}{\mathop{CH_2}}}-\underset{\underset{Br}{\mathop{|}}}{\overset{1}{\mathop{CH_2}}}}} $
