Answer: The molecule CH_{3}-CH_{3} is expected to have a dipole moment of zero.

Explanation:

The product of magnitude of the charge calculated in electrostatic units is called dipole moment.

Formula for dipole moment is as follows.

Dipole moment = Charge (in esu) \times distance (in cm)

Non-polar molecules have zero dipole moment.

For example, CH_{3}-CH_{3} is a non-polar molecule so its dipole moment is zero.

H_{2}C=O is a polar molecule so it will have dipole moment.

CH_{2}Cl_{2} is a polar molecule so it will have dipole moment.

NH_{3} has nitrogen atom as more electronegative than hydrogen atom. So, net dipole moment will be in the direction of nitrogen atom.

Thus, we can conclude that the molecule CH_{3}-CH_{3} is expected to have a dipole moment of zero.

Which factor is generally responsible for high melting points?
vlabodo [156]

A. High intermolecular forces of attraction. If there are high intermolecular forces, the molecules will need large energies to escape into the liquid. The substance will nave a high melting point.

The other options are <em>incorrect </em>because they are <em>weak force</em>s. They would cause <em>low melting points</em>.
