Which of the following species has a bond order of 2.5? A)N₂ B)NO⁺ C)CO D)O₂⁺ E)NO^-

Question

Quizplus · Accepted Answer

Bond order is defined as the number of bonds between two atoms. It can be calculated using the formula:Bond order = (number of bonding electrons - number of antibonding electrons) / 2For O2+, there are 10 valence electrons. Two of these electrons are used to form the sigma bond between the two oxygen atoms, and the remaining eight electrons are used to form four pi bonds. Two of the pi bonds are bonding, and two are antibonding. Therefore, the bond order of O2+ is (2 + 2 - 2) / 2 = 2.5.
