Question

Which of the following correctly identifies the intermolecular force represented by B and compares its strength relative to the intermolecular force represented by C?

A) B represents ion-dipole forces, which are weaker than the force represented by C.
B) B represents dipole-dipole forces, which are weaker than the force represented by C.
C) B represents ion-dipole forces, which are stronger than the force represented by C.
D) B represents dipole-dipole forces, which are stronger than the force represented by C.

Answer 1

B represents dipole-dipole forces, which are weaker than the force represented by C.

Step-by-step explanation:

The correct answer is B) B represents dipole-dipole forces, which are weaker than the force represented by C.

Dipole-dipole forces are attractive intermolecular forces between molecules with permanent dipoles. These forces arise due to the electrostatic attraction between the partial positive end of one molecule and the partial negative end of a neighboring molecule. They are generally stronger than dispersion forces but weaker than ionic bonds. Therefore, the force represented by B (dipole-dipole forces) is weaker than the force represented by C.
