Question 21 Mark
Alcohols are comparatively more soluble in water than hydrocarbons of comparable molecular masses. Explain this fact.
Answer
View full question & answer→Alcohol is a polar solvent. It form hydrogen bond with water molecules while hydrocarbons of comparable molecular masses does not form hydrogen bond due to being non-polar. Hence alcohol is more soluble in water.
Question 31 Mark
Explain why propanol has higher boiling point than that of the hydrocarbon, butane?
Answer
View full question & answer→The - OH group in propanol form intermolecular hydrogen bonding, thus it requires a lot of energy to break this hydrogen bond, as a result the boiling point increases. In butane the weak Van der Waals force of attraction present which requires less energy.

Question 341 Mark
Give reason for the higher boiling point of ethanol in comparison to methoxymethane.
Answer
View full question & answer→In ethanol, intermolecular H-bonding occurs. To break these hydrogen bonds, more energy is required. Whereas dipole-dipole attraction (Van der Waals force) is found in methoxymethane, required less energy to break bonds. Therefore the boiling point of ethanol is higher than that of hydroxymethane.
