Which of the following reagent is used for the following reaction?...

Which of the following reagent is used for the following reaction?

CH3CH2CH3→?CH3CH2CHO{CH}_{3}{CH}_{2}{CH}_{3}\overset{?}{\to}{CH}_{3}{CH}_{2}CHO

Options

  1. ACopper at high temperature and pressure
  2. BManganese acetate
  3. CMolybdenum oxide
  4. DPotassium permanganate

Correct answer

C. Molybdenum oxide

Step-by-step solution

CH3−CH2−CH3→Mo2O3CH3−CH2−CH=O{CH}_{3} - {CH}_{2} - {CH}_{3}\overset{{Mo}_{2}{O}_{3}}{\to}{CH}_{3} - {CH}_{2} - CH = O

The reagent used will be Mo2O3{Mo}_{2}{O}_{3} (molybdenum oxide) as this reagent always used to oxidise alkanes to aldehyde. So, it is widely used as an oxidation catalyst for acid-mediated catalytic reactions.
