Hydrocarbons Question 64
Question: What is the end product of the following sequences of operations $ CaC_2\xrightarrow{H_2O}A\underset{H{g^{++}}}{\mathop{\xrightarrow{dil\text{. }H_2SO_4}}}B\underset{H_2}{\mathop{\xrightarrow{Ni}}}C $ [CPMT 1978; MP PMT 1996]
Options:
A) Methyl alcohol
B) Acetaldehyde
C) $ C_2H_5OH $
D) $ C_2H_4 $
Show Answer
Answer:
Correct Answer: C
Solution:
$ CaC_2\xrightarrow{H_2O}\underset{Acetylene}{\mathop{HC\equiv CH}}\underset{H{g^{+2}}}{\mathop{\xrightarrow{Dil.H_2SO_4}}}\underset{Acetaldelyde}{\mathop{CH_3CHO}} $
$ \underset{H_2}{\mathop{\xrightarrow{Ni}}}\underset{Ethylalcohol}{\mathop{CH_3CH_2-OH}} $
