[Pb. PMT 1998]
Options:
A) The ion formed initially may react with $ B{r^{-}} $ or $ CH_3OH $
B) The methyl alcohol solvates the bromine
C) The reaction follows Markownikoff’s rule
D) This is a free-radical mechanism
Show Answer
Answer:
Correct Answer: A
Solution:
$ CH_2=CH_2+Br_2\xrightarrow{CH_3OH} $
$ \underset{Br}{\mathop{\underset{|}{\mathop{C}}H_2-}}\underset{Br}{\mathop{\underset{|}{\mathop{C}}H_2+}}Br-CH_2-CH_2-O-CH_3 $
