Hydrocarbons Question 207
Question: $ CaC_2+H_2O\to A\xrightarrow{H_2SO_4/HgSO_4}B $ . Identify A and B in the given reaction [CPMT 2000; BVP 2004]
Options:
A) $ C_2H_2 $ and $ CH_3CHO $
B) $ CH_4 $ and $ HCOOH $
C) $ C_2H_4 $ and $ CH_3COOH $
D) $ C_2H_2 $ and $ CH_3COOH $
Show Answer
Answer:
Correct Answer: A
Solution:
Wohler reaction : $ CaC_2+2H_2O\xrightarrow{{}}C_2H_2+Ca{{(OH)}_2} $
$ \underset{Acetylene}{\mathop{C_2H_2}}\underset{60^{o}C}{\mathop{\xrightarrow{dil.H_2SO_4/HgSO_4}}}\underset{Unstable}{\mathop{[CH_2=CHOH]}}\to \underset{Acetaldehyde}{\mathop{CH_3CHO}} $
