Statement-1: Bond order in a molecule can assume any value positive or negative, integral or fractional when the number of electrons in bonding molecular orbitals is greater than that in anti-bonding orbitals.
Statement-2: Bond order depends on the number of electrons in the bonding and antibonding orbitals.
Explanation:
Bond order is a measure of the strength and stability of a chemical bond. It represents the number of chemical bonds between a pair of atoms in a molecule.
Statement-1: Bond order in a molecule can assume any value positive or negative, integral or fractional when the number of electrons in bonding molecular orbitals is greater than that in anti-bonding orbitals.
This statement is true. The bond order is calculated as the difference between the number of bonding electrons and the number of anti-bonding electrons, divided by 2. If the number of bonding electrons is greater than the number of anti-bonding electrons, the bond order will be positive. If the number of anti-bonding electrons is greater than the number of bonding electrons, the bond order will be negative.
The bond order can also be fractional if there are partially filled bonding or anti-bonding orbitals. For example, in molecules with resonance structures, the bond order can be a fraction between two whole numbers. This indicates that the bond is partially formed and partially broken in different resonance forms.
Statement-2: Bond order depends on the number of electrons in the bonding and anti-bonding orbitals.
This statement is true. The bond order is directly proportional to the number of bonding electrons and inversely proportional to the number of anti-bonding electrons. As the number of bonding electrons increases, the bond order increases, indicating a stronger and more stable bond. Conversely, as the number of anti-bonding electrons increases, the bond order decreases, indicating a weaker and less stable bond.
Conclusion:
From the explanation above, we can conclude that Statement-1 is true and Statement-2 is true. However, Statement-2 provides a correct explanation for Statement-1. Therefore, the correct answer is option D) Statement-1 is False, Statement-2 is True.
