Free Liquids MCQs with Answers
350 Liquids MCQs from Chemistry, each with the correct answer and a written explanation of why it is correct. Free and unlimited, with no account needed.
Liquid properties arise from intermolecular attractions, including surface tension, viscosity, cohesion and adhesion. The topic links evaporation, vapour pressure and boiling point with temperature, explains hydrogen bonding, and covers water's unusual expansion on freezing and its density maximum, which distinguish water from ordinary liquids.

Explanation: London forces are caused by movement of electrons leading to instantaneous dipoles.
Correct answer: London forces- A. Gases only
- B. Liquids only
- C. Solids only
- D. All of the above
Explanation: The London dispersion force is the weakest intermolecular force. The London dispersion force is a temporary attractive force that results…
Correct answer: All of the above- A. Decrease in surface tension of water
- B. Viscosity of water
- C. High boiling point of water
- D. Polarity of water
Explanation: Polarity of water: Soap molecules have polar and nonpolar regions, allowing them to interact with both water and oily substances…
Correct answer: Polarity of water- A. London forces are present in non-polar molecules.
- B. London forces are present in polar molecules.
- C. London forces are created between an instantaneous dipole and an induced dipole.
- D. All of the above.
Explanation: London dispersion forces are a type of van der Waals force and are the weakest intermolecular force.
Correct answer: All of the above.347. An Azeotropic mixture of two miscible liquids boils at a lower temperature than its components when:
- A. The system shows a negative deviation from Raoult's law.
- B. The system shows a positive deviation from Raoult's law.
- C. The system perfectly obeys Raoult's law
- D. Both (A) and (B)
Explanation: An azeotropic mixture is a combination of liquids that behave as a single substance with a consistent boiling point and consistent vapor…
Correct answer: The system shows a positive deviation from Raoult's law.- A. These parts of the body are warmer than the surroundings
- B. These parts of the body are cooler than the surroundings
- C. These parts of the body are constantly increasing and decreasing with the temperature
- D. None of the above options are correct
Explanation: Liquid crystalline substances are used to locate the viens, arteries, infections, and tumors.
Correct answer: These parts of the body are warmer than the surroundings- A. Diethyl ether
- B. Benzene
- C. Carbon disulphide
- D. Carbon tetrachloride
Explanation: When we compare the boiling points of different substances, we look at the intermolecular forces between their molecules.
Correct answer: Benzene- A. Both polar and non - polar molecules
- B. Non - polar molecules
- C. Polar molecules
- D. Statement is wrong
Explanation: London dispersion forces are present in all atoms and molecules, regardless of their size or composition.
Correct answer: Statement is wrong
