Question

Which of the following molecules is nonpolar? CO, NO, ALCL3, SO2

Answer 1

The nonpolar molecule out of the given options is CO (carbon monoxide).

Step-by-step explanation:

A nonpolar molecule is one that has an equal distribution of electrons, resulting in no permanent positive or negative charges. To determine if a molecule is nonpolar, we need to consider the polarity of its individual bonds as well as its molecular geometry.

Out of the given options, the molecule that is nonpolar is CO. Carbon monoxide (CO) has a linear molecular geometry and a polar bond between the carbon and oxygen atoms. However, the molecule overall is nonpolar because the dipole moments of the polar bonds cancel each other out.

Answer 2

The answer is AlCl3

Step-by-step 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.
