Answer:

The answer is AlCl3

Explanation:

Aluminum chloride is a salt made of aluminum and chlorine. It is presented as a yellow powder thanks to impurities due to the presence of iron chloride. AlCl3 is flat trigonal, and it is not polar. Their dipole moment of each Al-Cl links have angles of 120 degrees to each other and, therefore, are canceled. This is why this molecule is nonpolar.
