Question:
The correct order of bond enthalpy of given molecules is
The correct order of bond enthalpy of given molecules is
Show Hint
When studying bond enthalpies, remember that multiple bonds (double or triple) typically lead to higher bond enthalpies.

- O$_2$<N$_2$<H$_2$
- N$_2$<O$_2$<H$_2$
- H$_2$<N$_2$<O$_2$
- H$_2$<O$_2$<N$_2$
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The bond enthalpy of a molecule increases as the bond order increases. The correct order of bond enthalpy is H$_2$<O$_2$<N$_2$. This is because N$_2$ has a triple bond, which is stronger, while H$_2$ has the weakest bond due to its single bond.
