Step 1: Recall the bond dissociation energies for the given bonds.
The bond dissociation energy is the energy required to break a chemical bond. For the given options, we have: - N-N single bond: 160 kJ/mol - N=N double bond: 418 kJ/mol - N≡N triple bond: 941 kJ/mol
Step 2: Compare the bond dissociation energies to determine which bond has the highest energy.
To find the bond with the highest bond dissociation energy, we simply compare the given values: - N-N: 160 kJ/mol - N=N: 418 kJ/mol - N≡N: 941 kJ/mol
Final Answer
The N≡N triple bond has the highest bond dissociation energy.
