Questions & Step-by-Step Solutions
Which of the following pairs of molecules has the same bond order?
Step 1: Understand what bond order means. Bond order is a measure of the number of chemical bonds between a pair of atoms.
Step 2: Recall the formula for bond order: Bond Order = (Number of bonding electrons - Number of antibonding electrons) / 2.
Step 3: Analyze the molecular structure of N2 (Nitrogen gas). N2 has 10 bonding electrons and 0 antibonding electrons. So, Bond Order = (10 - 0) / 2 = 5.
Step 4: Analyze the molecular structure of CO (Carbon Monoxide). CO has 10 bonding electrons and 2 antibonding electrons. So, Bond Order = (10 - 2) / 2 = 4.
Step 5: Compare the bond orders of N2 and CO. N2 has a bond order of 3, and CO also has a bond order of 3.
Step 6: Conclude that N2 and CO have the same bond order.
