For which of the following pairs of molecules is the bond order the same?

For which of the following pairs of molecules is the bond order the same?

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: Identify the molecules in the question: O2 (oxygen) and F2 (fluorine).
Step 3: Determine the bond order for O2. O2 has a double bond, which means its bond order is 2.
Step 4: Determine the bond order for F2. F2 also has a single bond, which means its bond order is 1.
Step 5: Compare the bond orders of O2 and F2. O2 has a bond order of 2, while F2 has a bond order of 1.
Step 6: Conclude that O2 and F2 do not have the same bond order.

Bond Order – Bond order is a measure of the number of chemical bonds between a pair of atoms, calculated as the difference between the number of bonding and antibonding electrons divided by two.
Molecular Orbital Theory – This theory explains the formation of molecular bonds in terms of the combination of atomic orbitals to form molecular orbitals, which can be occupied by electrons.
