Question

Arrange the bonds in order based on bond length. Start with the longest bond, and end with the shortest bond.

C≡N
bond energy = 887 kJ/mol
C=N
bond energy = 615 kJ/mol
C–N
bond energy = 305 kJ/mo

Answer 1

Answer: C-N(Longest) > C=N > CN(C triple bond N, shortest)

Explanation: Bond length is the distance between nuclei of bonded atoms.

Bond energy is the which needs to break the bond.

And bond length is always inversily proportional to bond energy.

Larger the bond energy ,shorter the bond length
