Question
How would you convert:
  1. Ethanol into ethene?
  2. Propanol into propanoic acid?
Name the process in each case and write the equations of the reactions involved.

Answer

  1. Dehydration: Conversion of ethanol into ethene.

$\text{CH}_3-\text{CH}_2\text{OH}\xrightarrow[{(\text{Dehydration})}]{{ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \text{Cons.}\text{H}_2\text{SO}_4;170^\circ\text{C}}\ \ \ \ \ \\ \ \ \ \ \ \ \ }\text{CH}_2=\text{CH}_2+\text{H}_2\text{O}$

  1. Oxidation: Conversion of propanol acid.

​​​​​​$\text{CH}_3\text{CH}_2\text{CH}_2\text{OH}+2[\text{O}]\xrightarrow[{\text{or}\ \text{acidified}\text{K}_2\text{Cr}_2}\text{O}_7]{{ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \text{Alkaline}\text{KmnO}_4;\text{Heat}}\ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ }\text{CH}_3\text{CH}_2\text{COOH}+\text{H}_2\text{O}$
