हिन्दीGiven below are two statements: Statement I: With increase in bond order, bond enthalpy decreases and bond length increases. Statement II: Isoelectronic molecules and ions such as \( \text{F}_2 \) and \( \text{O}_2^{2-} \) have identical bond orders. In the light of the above statements, choose the most appropriate answer from the options given below:
Correct answer · Option 4
Statement I is incorrect but Statement II is correct.
Explanation
Statement I is incorrect because with increase in bond order, bond enthalpy increases and bond length decreases. Statement II is correct as both \( \text{F}_2 \) and \( \text{O}_2^{2-} \) have 18 electrons and a bond order of 1.
