Which of the following reagent is used for the following reaction ? CH3CH2CH3 → CH3CH2CHO

1. Manganese acetate
2. Copper at high temperature and pressure
3. Molybdenum oxide
4. Potassium permanganate

Correct answer: Molybdenum oxide

Solution

Direct oxidation of propane (CH3CH2CH3) to propanal (CH3CH2CHO) is achieved by catalytic oxidation over molybdenum oxide (MoO3-based catalyst), which selectively abstracts hydrogen to give the aldehyde.
