Question

if a molecule contains polar bonds, the molecule may or may not be polar overall.
options: false (green), true (blue)

Explanation:

To determine the answer, we analyze the concept of molecular polarity. A molecule with polar bonds can be non - polar if the polar bonds are arranged symmetrically, canceling out the dipole moments (e.g., $\ce{CO_2}$ has polar $\ce{C=O}$ bonds but is non - polar due to linear symmetry). If the polar bonds are arranged asymmetrically, the molecule is polar (e.g., $\ce{H_2O}$). So a molecule with polar bonds may or may not be polar overall.

Answer:

True
