Alcohols Phenols And Ethers Question 125
Question: Ethanol can be prepared more easily by which reaction-
(i) $ CH_3CH_2Br+H_2O\xrightarrow{{}}CH_3CH_2OH $ (ii) $ CH_3CH_2Br+Ag_2O( inboilingwater )\xrightarrow{{}} $ $ CH_3CH_2OH $
Options:
A) by (i) reaction
B) by (ii) reaction
C) Both reactions proceed at same rate
D) by none
Show Answer
Answer:
Correct Answer: B
Solution:
[b] Heavy metal ions, particularly $ A{g^{+}} $ catalyse $ S _{N}1 $ reaction because of the presence of empty orbital. $ CH_3CH_2Br+A{g^{+}}\rightarrow {{[CH_3CH_2\cdot \cdot \cdot X\cdot \cdot \cdot Ag]}^{+}} $
$ \xrightarrow[(-AgX)]{slow}CH_3CH_2^{+}\xrightarrow[fromH_2O]{O{H^{-}}}CH_3CH_2OH $
