Methanol is prepared from carbon monoxide and hydrogen. The catalyst used for this reaction is:
Correct answer: D. Cr2O3 + ZnO
- A. ZnO + CoO2
- B. ZnO + CuO
- C. ZnO + Ag2O
- D. Cr2O3 + ZnO
Explanation
A is incorrect as CoO2 is not used as a catalyst in the preparation of methanol.B is incorrect as CuO2 is not used as a catalyst in the preparation of methanol.C is incorrect as Ag2O is not used as a catalyst in the preparation of methanol.D is correct as Cr2O3 is used as a catalyst in the preparation of methanol. CO + H2 → CH3 + OH (reaction)

About Alcohols
Alcohols contain a hydroxyl group attached to a saturated carbon atom and are classified as primary, secondary or tertiary. Their nomenclature, hydrogen bonding, acidity, oxidation, dehydration, reaction with sodium and conversion to haloalkanes are covered, along with the distinction between alcohols and phenols, where the hydroxyl group is attached directly to an aromatic ring.
