Final answer:
A molecule that contains at least one polar covalent bond but is nonpolar is called a polar covalent bond. An example of such a molecule is carbon dioxide (CO2).
Step-by-step explanation:
A molecule that contains at least one polar covalent bond but is nonpolar is called a polar covalent bond.
This type of bond occurs when there is a difference in electronegativity between the atoms involved, but the molecular structure cancels out the dipole moments, resulting in a nonpolar molecule.
An example of such a molecule is carbon dioxide (CO2), where the carbon-oxygen bonds are polar covalent but the molecule itself is nonpolar due to its linear structure.
