Alcohols Phenols And Ethers Question 75
Question: Which is the best reagent to convert isopropyl alcohol to isopropyl bromide- $ CH_3-\overset{CH_3}{\mathop{\overset{|}{\mathop{C}}}}H-OH\xrightarrow{-}CH_3-\overset{CH_3}{\mathop{\overset{|}{\mathop{C}}}}H-Br $
Options:
A) $ HBr $
B) $ SOBr_2 $
C) $ Br_2 $
D) $ CH_3MgBr $
Show Answer
Answer:
Correct Answer: B
Solution:
[b] $ CH_3-\overset{CH_3}{\mathop{\overset{|}{\mathop{C}}}}H-OH\xrightarrow{SOBr_2} $
$ CH_3-\overset{CH_3}{\mathop{\overset{|}{\mathop{C}}}}H-Br+SO_2+HBr $ Side products are gases. In case of $ HBr $ elimination also favours to produce alkene.
