Both carbon dioxide (CO) and water (H2O) are molecular compounds made up of three atoms. Which has a linear shape, and why?
OA. carbon dioxide only, because its central atom lacks any unbonded electron pairs
B. water only, because its central atom lacks any unbonded electron pairs
OC. neither molecule, because all three-atom molecules have bent shapes
OD. both molecules, because oxygen atoms always have unbonded electron pairs


Sagot :

Final answer:

Carbon dioxide is linear and nonpolar, while water is bent and polar.


Explanation:

Carbon dioxide (CO₂) is a linear molecule due to its molecular geometry. The dipoles of the two C=O bonds cancel out, resulting in a nonpolar molecule. On the other hand, water (H₂O) has a bent shape due to the lone pairs on the central oxygen atom, making it a polar molecule.
