उत्तर १
\[\ce{Ethane -> Alcohol}\]
\[\ce{2C2H6 + O2 ->[Cu][200°C] 2C2H5OH}\]
The alcohol is ethanol.
उत्तर २
When a mixture of ethane and oxygen in the ratio 9 : 1 by volume is compressed to about 120 atm pressure and passed over copper tubes at 475K, ethyl alcohol is formed.
\[\ce{2C2H6 + O2 ->[120atm][Cutubes 475K] 2C2H5OH}\]
