Question

question 10 / 10
a molecule can have polar bonds but be nonpolar overall. which factor is responsible for this?
a. a very high molecular weight.
b. the substance being a gas at room temperature.
c. an equal number of atoms of each element.
d. a symmetrical molecular shape.

Explanation:

Polar bonds occur when there is a difference in electronegativity between atoms. However, if a molecule has a symmetrical shape, the bond - dipoles can cancel each other out, resulting in a nonpolar overall molecule. Molecular weight, state at room temperature, and equal number of atoms of each element do not directly determine overall molecular polarity when polar bonds are present.

Answer:

D. A symmetrical molecular shape.
