Which of the following is TRUE regarding Methyl Alcohol?
Correct answer: A. It is a colorless, volatile, thin liquid with specific gravity 0.796 at 15°C.
- A. It is a colorless, volatile, thin liquid with specific gravity 0.796 at 15°C.
- B. It is used for low-temperature thermometers and as a fuel substitute.
- C. It is extensively used in the formation of different beverages.
- D. It is used as a base for perfumes.
- E. It is used as an antiseptic and disinfectant.
Explanation
Methyl Alcohol, also known as methanol, is a colorless, volatile, and thin liquid with a specific gravity of 0.796 at 15°C. This makes Option A the correct choice. Methyl Alcohol is primarily used as an industrial solvent and antifreeze, and is not suitable for consumption or use in perfumes due to its toxicity. Options B and C describe Ethanol, which is used in thermometers and beverages. Option D describes esters, often used in perfumes. Option E describes Phenol, which is used as an antiseptic and disinfectant.

About Alcohols and Phenols
Alcohols are classified as primary, secondary or tertiary and studied through their hydrogen bonding, acidity, oxidation and reactions with active metals, acids and halogenating agents. Phenols require separate treatment because the hydroxyl group is attached to an aromatic ring, making their acidity and electrophilic substitution different from ordinary alcohols.
