    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.
