Which one of them is used as an automobile antifreeze?
Correct answer: C. Ethylene glycol
- A. Ethanol
- B. Ethene
- C. Ethylene glycol
- D. Propene
Explanation
Option A: Ethanol is not used as automobile antifreeze. Ethanol is a type of alcohol that is commonly used as a fuel additive or solvent. Option B: Ethene is not used as an automobile antifreeze because it is a gas at room temperature and pressure and does not have the necessary properties for use as an antifreeze. Option C: Ethylene glycol (antifreeze) is used in the cooling of a car radiator during the winter because it has a much lower freezing point than water. Its role in an automobile is to absorb heat from the engine. Option D: Propene is not used as automobile antifreeze. Propene is a hydrocarbon that is used as a feedstock for the production of plastics and other chemicals.

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.
