Methyl alcohol is not used as___________________?
Correct answer: C. a substitute for petrol
- A. a solvent
- B. an anti freezing agent
- C. a substitute for petrol
- D. for denaturing of ethyl alcohol
Explanation
Methanol is widely used as a solvent, antifreeze, and denaturant for ethanol because it makes alcohol unsuitable for drinking. It can be used as a fuel or fuel additive, but it is not ordinarily described in this context as a substitute for petrol. The likely mistake is choosing d because methanol is poisonous, but that poisonous property is precisely why it is used for denaturing ethanol.

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.
