what is the easiest way to determine whether a molecular structure is polar or non - polar?
add up the dipole moments for a 3 - dimensional structure. if the dipole moments sum to zero the structure is non - polar. if the dipole moments do not sum to zero, the structure is polar.
draw a 3 - dimensional structure. if it is symmetrical, it is non - polar. if it is asymmetrical, it is polar.

Explanation:

To determine if a molecular structure is polar or non - polar, we can consider the symmetry of its 3 - dimensional structure. Symmetrical structures have dipoles that cancel out (sum to zero), making them non - polar. Asymmetrical structures have dipoles that do not cancel (do not sum to zero), making them polar.

Answer:

A. Add up the dipole moments for a 3 - dimensional structure. If the dipole moments sum to zero the structure is non - polar. If the dipole moments do not sum to zero, the structure is polar.
