Free Properties of Liquids MCQs with Answers
145 Properties of 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 behavior depends on intermolecular forces, which produce surface tension, viscosity, capillary action and a definite volume without a fixed shape. The topic also covers vapor pressure, evaporation, boiling point and the effect of temperature and external pressure, while distinguishing evaporation at the surface from boiling throughout the liquid.

- 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.142. 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
