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.

- B. Water forms dative bonding
- C. Water molecule is polar
- D. Water has high density
Explanation: To dissolve an ionic compound, the water molecules must be able to stabilise the ions that result from breaking the ionic bond.
Correct answer: Water molecule is polar- A. Dipole dipole forces
- B. Debye forces
- C. London dispersion forces
- D. H-bonding
Explanation: London's dispersion forces are the weakest of all the intermolecular forces.
Correct answer: London dispersion forces125. Liquids have _.
- A. Definite volume
- B. Indefinite volume
- C. Irregular volume
- D. Changing volume
Explanation: The state of matter, which has a definite volume but no definite shape, is called liquid.In liquids, the molecules are close to each…
Correct answer: Definite volume- A. H-bonding
- B. London dispersion forces
- C. Dipole-dipole force
- D. Chemical bonding
Explanation: B is correct option because Iodine sublimes rather than melting and boiling.
Correct answer: London dispersion forces- A. Anisotropic liquids
- B. Nematic liquids
- C. Isotropic liquids

Explanation: a) Anisotropic liquids Anisotropic liquids are liquids that have different physical properties in different directions.
Correct answer: Anisotropic liquids128. Liquids have _ ?
- A. Definite shape
- B. Indefinite shape
- C. Indefinite volume
- D. None of these
Explanation: Liquids do not have any definite shape however definite volume.
Correct answer: Indefinite shape- A. Friedrich Reinitzer
- B. William Crooks
- C. Bravis
- D. J. J. Thomson
Explanation: Liquid crystal was discovered by Friedrich Reinitzer, an Austrian botanist and chemist, in 1888.
Correct answer: Friedrich Reinitzer- A. -188.1
- B. 188.1
- C. 184.4
- D. -184.4
Explanation: Fluorine, the most reactive chemical element and the lightest member of the halogen elements and has a boiling point, −188 °C (−306 °F).
Correct answer: -188.1- A. Lower than gases
- B. Higher than solids
- C. Lower than solids
- D. Both A and B
Explanation: When a solid changes into a liquid the atoms inside experience two variations.
Correct answer: Both A and B- A. Sulphur.
- B. Phosphorous
- C. Argon
- D. Sugar.
Explanation: London forces are significant in noble gases like argon. Noble gases are known for their weak intermolecular interactions, mainly London…
Correct answer: Argon- A. Alcohol-ether.
- B. Nicotine-water.
- C. Benzene-water.
- D. Both A and B.
Explanation: The nicotine-water system has an LCST of 61 °C, and also a UCST of 210 °C at pressures high enough for liquid water to exist at that…
Correct answer: Nicotine-water.- A. Dipole-dipole forces
- B. Dipole-induced dipole forces
- C. London dispersion forces
- D. Hydrogen bonding
Explanation: A is incorrect because dipole-dipole forces only occur in polar molecules.B is incorrect as dipole-induced dipole forces are present…
Correct answer: London dispersion forces- A. Atoms of helium in gaseous state at high temperature
- B. Molecules of water
- C. Molecules of NH3
- D. Molecules of HCl gas
Explanation: Option A is correct because helium atoms are non-polar and only exhibit London dispersion forces.
Correct answer: Atoms of helium in gaseous state at high temperature- A. boiling point
