Answer: Methanol.
- A Ethylene glycol
- B Formaldehyde
- C Acetic acid
- D Methanol
Correct answer: D. Methanol
Explanation: Catalytic combination of CO and H<sub>2</sub> (synthesis gas) yields methanol, an important industrial hydrogenation of carbon monoxide.
Each water molecule's O-H bonds (covalent, solid) can hydrogen-bond (dashed) to neighbouring molecules, forming an extended network responsible for water's unusually high boiling point and density anomaly.
