Answer:

B. Dipole-dipole

Explanation:

Dipole-dipole is an intermolecular force between polar molecules, where the positive end of one molecule is attracted to the negative end of the second molecule. Polar molecules form dipoles because they contain both electron-rich and electron-deficient regions, thus containing a partial positive pole and a partial negative pole within the same molecule. Examples of molecules that form dipole-dipole interactions include acetone and formaldehyde.

The intermolecular force acting in CH3CH3 is the dispersion forces.

The nature of intermolecular forces between molecules depends on the polarity of the molecules. Nonpolar polar molecules only have weak dispersion forces acting between their molecules.

The molecule CH3CH3 is a nonpolar molecule. Since it is nonpolar, the only intermolecular force acting between its molecules is the weak dispersion forces.
