Refer to diagram 9-1.Identify the molecule or ion with the longest bond length. A) O₂ B) O₂⁺ C) O₂^- D) O₂^2- E) O₂²⁺

Question

Quizplus · Accepted Answer

The molecule with the longest bond length is the one with the fewest double bonds. In option D, there are no double bonds, while in options B and E there is a double bond between the phosphorus and one of the sulfur atoms. Option A has a double bond between the two sulfur atoms. Option C has both a double bond between the phosphorus and sulfur and a negative charge, contributing to shorter bonds. Therefore, option D, with no double bonds, has the longest bond length.
