Which of the following reactions takes places when tertiary butanol passed over heated copper at 573 ~K ?

Options

  1. ADehydrogenation reaction
  2. BDehydration reaction
  3. COxidation reaction
  4. DAddition reaction

Correct answer

B. Dehydration reaction

Step-by-step solution

When tertiary butanol (3^ . alcohol ) is passed over heated Cu at 573 ~K , isobutene is formed through elimination reaction. Since, water gets eliminated, so it is also considered as dehydration reaction. The 2^ alcohol and 1^ alcohol on the other hand gives ketone and aldehyde respectively in similar reaction.
