Which of the following molecules has a bond order of 2?

Which of the following molecules has a bond order of 2?

Correct Answer: N2

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. In this case, we are looking at N2 (nitrogen gas).
Step 4: Determine the number of bonding and antibonding electrons in N2. N2 has 10 bonding electrons and 6 antibonding electrons.
Step 5: Plug the numbers into the bond order formula: (10 - 6) / 2.
Step 6: Calculate the result: 4 / 2 = 2.
Step 7: Conclude that N2 has a bond order of 2.
