Show Answer
Answer:
Correct Answer: B
Solution:
$ CH_2=CH_2+H_2O+[O]\xrightarrow{alk.KMnO_4}\underset{Glycol}{\mathop{\underset{OH}{\mathop{\underset{|}{\mathop{CH_2}}}}-\underset{OH}{\mathop{\underset{|}{\mathop{CH_2}}}}}} $
$ \underset{Ethene}{\mathop{CH_2=CH_2}}+H_2O\xrightarrow{Conc\text{.}H_2SO_4}\underset{Ethanol}{\mathop{CH_3-CH_2-OH}} $
