Question

Identify the bond with the lowest bond energy.

C=C

Si=O

C=N

O=O

N=N How do I go about solving this on a test?

Answer 1

For the bond with same atoms will have lower anergy then the bond with two different atoms

So Si=O has highest bond energy because of large electronegativity difference

Then second highest bond energy is with C=N because of different atoms

These two had highest bond energies

Now we have O=O and N=N and C=C

Lowest bond energy is with N=N and second lowest is with O=O and highest among these three is C=C

Final answer is : N=N
