Question

question 6 of 10 which of these molecules is nonpolar? a. o₂ b. co c. ch₃cl d. pf₃

Explanation:

A non - polar molecule has an even distribution of charge. In $O_2$, the two oxygen atoms have the same electronegativity, so the electron - pair is shared equally between them, resulting in a non - polar molecule. In $CO$, there is a difference in electronegativity between carbon and oxygen, creating a polar bond and a polar molecule. In $CH_3Cl$, the presence of the more electronegative chlorine atom causes an uneven distribution of charge, making it polar. In $PF_3$, the lone pair on phosphorus and the difference in electronegativity between phosphorus and fluorine lead to a polar molecule.

Answer:

A. $O_2$
