Which of the following molecules will have the largest bond angle?

Possible Answers:

Correct answer:


According to VSEPR theory, atoms will orient themselves in order to be as far away from neighboring atoms as possible in a molecule. This theory helps predict the geometry that molecules will take, as well as the bond angles between atoms.

 is formed by a central carbon bound to two adjacent oxygen atoms. To maximize the distance between the oxygen atoms, they will align at an angle of 180 degrees, creating a linear shape.

All of the other given moleules will have bond angles less than 180 degrees.
