Question

The liquid which has the highest rate of evaporation is:

• A. Petrol
• B. Water
• C. Nail- polish remover
• D. alcohol

Answer 1

The correct option is C

Nail- polish remover

Explanation for the correct option:

C) Nail- polish remover

• Acetone is present in nail polish remover.
• In the case of acetone, there is no hydrogen bonding between the molecules. As a result, they have the greatest rate of evaporation.
• Acetone, which is found in nail polish remover, has a rapid rate of vapor pressure owing to its poor intermolecular force of attraction.

Explanation for the incorrect options:

(A) Petrol

• Petrol is a combination of nonpolar hydrocarbons with weak London dispersion forces amongst them.
• Petrol has modest London dispersion forces among its molecules.
• Thus petrol has a low rate of evaporation than nail polish remover.
• Hence this option is not correct.

(B) Water

• Water is a strongly polar molecule having hydrogen bonding among its molecules,
• Water has higher intermolecular interactions between its molecules in the form of hydrogen bonding.
• Thus water has a low rate of evaporation.
• Hence this option is not correct.

(D) alcohol

• Alcohols have two forms of intermolecular attraction forces: hydrogen bonding and Van der Waals.
• Thus alcohol has a low rate of evaporation than nail polish remover.
• Hence this option is not correct.

Hence, the correct option is (C) i.e., Nail- polish remover.
