Which of the following molecules has a bond order of 1?

Which of the following molecules has a bond order of 1?

Correct Answer: Li2

Step 1: Understand what bond order means. Bond order is a way to measure the strength and stability of a bond between two atoms.
Step 2: Know the formula for calculating bond order: (Number of bonding electrons - Number of antibonding electrons) / 2.
Step 3: Identify the molecule in question, which is Li2 (Lithium molecule).
Step 4: Determine the number of bonding electrons in Li2. For Li2, there are 2 bonding electrons.
Step 5: Determine the number of antibonding electrons in Li2. For Li2, there are 0 antibonding electrons.
Step 6: Plug the numbers into the bond order formula: (2 bonding electrons - 0 antibonding electrons) / 2.
Step 7: Calculate the bond order: (2 - 0) / 2 = 2 / 2 = 1.
Step 8: Conclude that Li2 has a bond order of 1.
