Chemistry · CHEMICAL BONDING AND MOLECULAR STRUCTURE
हिन्दीWhich of the following diatomic molecules has the highest bond dissociation enthalpy?
Correct answer · Option 4
\( \text{N}_2(\text{g}) \)
Explanation
The bond dissociation enthalpy of \( \text{N}_2 \) is \( 946.0\text{ kJ mol}^{-1} \), which is higher than that of \( \text{H}_2 \) (\( 435.8\text{ kJ mol}^{-1} \)), \( \text{HCl} \) (\( 431.0\text{ kJ mol}^{-1} \)), and \( \text{O}_2 \) (\( 498\text{ kJ mol}^{-1} \)).
