Question

predict which of the following molecules will demonstrate the least polarity.
secl4
co
clo-
o2

Explanation:

Molecular polarity depends on bond polarity and molecular geometry. A nonpolar molecule has symmetric charge distribution. $\text{O}_2$ is diatomic with identical oxygen atoms, so the bond is nonpolar (electronegativity difference = 0), making the molecule nonpolar. Other options have polar bonds and/or asymmetric shapes leading to polarity.

Answer:

O₂
