When vapours of isopropyl alcohol is passed over heated copper, we get acetone. It is an example for

• A

  dehydration
• B

  dehalogenation
• C

  dehydrohalogenation
• Correct answer
  D

  dehydrogenation

Solution

Alcohols are oxidised by passing their vapours over heated copper. $2^{\circ}$ alcohol (isopropyl alcohol) is oxidised to acetone i.e. it undergoes dehydrogenation as follows :

Hence, the correct answer is option: 'D'.
