If a molecule demonstrates paramagnetism, then: The substance can have both paired and unpaired electrons. The bond order is not a whole number. It can be determined by drawing a Lewis structure. It must be an ion. I. II. IV. O A. I, I O B. I, II, IV O C. I, II D.I only E. All of the above are correct.

22. Use the molecular orbital energy diagram shown to determine which of the following is most stable (has highest bond order). A. C₂² B. N₂2 C. B₂ D. C₂2 E. B₂2

Use the molecular orbital energy diagram below to answer the questions about bond order for the molecule Ne2. Number of Number of Bonding electrons Antibonding electrons This corresponds to: A. Single bond Double bond B. C. Triple bond D. Half of a bond Ne2 Bond Order E. Between a single and double bond F. Between a double and a triple bond G. No bond, Ne2 does not form

Use molecular orbital diagrams to determine the number of unpaired electrons in: a. C₂²- b. C₂+ C. BN d. NO
