Which of the following bonds has highest bond enthalpy?
- A \(\mathrm{N}-\mathrm{H}\) in \(\mathrm{NH}_3\)
- B \(\mathrm{O}=\mathrm{O}\) in \(\mathrm{O}_2\)
- C \(\mathrm{C}-\mathrm{H}\) in \(\mathrm{CH}_4\)
- D \(\mathrm{N} \equiv \mathrm{N}\) in \(\mathrm{N}_2\)
Answer & Solution
Correct Answer
(D) \(\mathrm{N} \equiv \mathrm{N}\) in \(\mathrm{N}_2\)
Step-by-step Solution
Detailed explanation
More the number of bonds between atoms more will be the bond energy.
\(\mathrm{N}_2\) has triple bond between \(\mathrm{N}\) atoms and has highest bond enthalpy.
\(\mathrm{N}_2\) has triple bond between \(\mathrm{N}\) atoms and has highest bond enthalpy.
