CHM 101 Chemical Bonding and Intermolecular Forces Objective Question

Question

In the context of intermolecular forces, what is polarizability?
Options
A The ability of a molecule to form hydrogen bonds
B The tendency of an electron cloud to distort, creating temporary dipoles
Correct Answer
C The strength of an ionic bond
D The measure of a molecule's permanent dipole moment
Correct Answer

Option B is the correct answer.

Detailed Explanation

Polarizability is the tendency of an electron cloud to distort in response to an external electric field or the presence of a neighboring dipole. This distortion leads to the formation of temporary, instantaneous dipoles that contribute to London dispersion forces.

Hint

Larger atoms with more electrons are more easily polarizable.
