Which type of force is present in gasoline?
Correct answer: C. London dispersion forces
- 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 between polar and non-polar molecules.C is correct as london dispersion forces occur between non polar molecules and gasoline is non polar.D is incorrect as hydrogen bonding only occurs between atoms with high electro-negativity.

About Properties of Liquids
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.
