Understanding Bond Order
Bond order is a crucial concept in molecular chemistry that provides insights into the strength and stability of bonds between atoms. Let’s explore why option 'B' is the incorrect statement regarding bond order.
What is Bond Order?
- Bond order refers to the number of chemical bonds between a pair of atoms.
- For example, a single bond has a bond order of 1, a double bond has a bond order of 2, and a triple bond has a bond order of 3.
Analysis of Option B
- Option B states: "With increase in bond order, bond enthalpy of the molecule decreases."
- This statement is false because:
- Bond Entropy Dynamics: As bond order increases, the number of shared electron pairs between the atoms also increases, leading to stronger bonds.
- Bond Strength Correlation: Higher bond order typically correlates with increased bond strength (enthalpy). Stronger bonds require more energy to break, hence bond enthalpy increases with bond order.
Comparative Validity of Other Options
- Option A: Correct – It accurately defines bond order.
- Option C: Correct – Isoelectronic species often exhibit the same bond order due to similar electron configurations.
- Option D: Correct – As bond order increases, bond length decreases due to increased electron density between the nuclei.
Conclusion
In summary, option 'B' is not valid. With an increase in bond order, bond enthalpy actually increases, highlighting the strength and stability of the bond rather than a decrease. Understanding these concepts is essential for mastering molecular bonding in chemistry, especially for NEET preparation.
