Question

what is a non-polar molecule?
a. a molecule with a positive charge
b. a molecule with an uneven distribution of electrons
c. a molecule with a negative charge
d. a molecule with an even distribution of electrons

Explanation:

To determine the correct answer, we analyze each option:

• Option a: A molecule with a positive charge is an ion (cation), not a non - polar molecule. Non - polar molecules are neutral overall.
• Option b: An uneven distribution of electrons leads to a polar molecule, as it creates a dipole moment (separation of positive and negative charges within the molecule).
• Option c: A molecule with a negative charge is an ion (anion), not a non - polar molecule. Non - polar molecules are electrically neutral.
• Option d: A non - polar molecule has an even (symmetrical) distribution of electrons, which means there is no net dipole moment and the molecule is electrically neutral overall.

Answer:

d. A molecule with an even distribution of electrons
