Complete the following reaction R C O O H → P 2 O 5 ∆ ?

Options

  1. AAcid anhydride
  2. BKetone
  3. CAldehyde
  4. DEster

Correct answer

A. Acid anhydride

Step-by-step solution

P 2 O 5 is dehydrating agent, hence acid gives anhydrides on dehydration by P 2 O 5 . 2 R C O O H → P 2 O 5 - H 2 O R C O 2 O
