प्रश्न
Under what conditions does ethane get converted to ethyl alcohol?
Advertisements
उत्तर १
Ethane is mixed with oxygen and is passed through a hot copper tube; it gets oxidized to ethyl alcohol.
\[\ce{2C2H6 + O2 ->[Cu][200^\circ C] 2C2H5OH}\]
उत्तर २
Step 1: C2H6 is converted into C2H5Cl.
\[\ce{C2H6 + Cl2 -> C2H5Cl + HCl}\]
Step 2: By hydrolysis of ethyl halides.
\[\ce{\underset{[Ethyl chloride]}{C2H5Cl} + NaOH -> \underset{[Ethyl alcohol]}{C2H5OH} + NaCl}\]
