Alcohols of lower Molecular weight are _______________?
Correct answer: A. More Soluble in water
- A. More Soluble in water
- B. Insoluble in water
- C. Soluble in water on heating
- D. Insoluble in all solvents
Explanation
Lower molecular-weight alcohols are relatively soluble in water because their polar hydroxyl group forms hydrogen bonds with water, and the small hydrocarbon group does not strongly oppose mixing. As the carbon chain becomes longer, the nonpolar part increases and solubility decreases. Students may choose soluble only on heating, but lower alcohols are already appreciably soluble at ordinary temperature.

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.
