Chapter 6.6, Problem 6.6CE

Interpretation Introduction

Interpretation:

The decreasing order bond length for the $\text{C=N, C}\equiv \text{N,}\text{and}\text{C-N}$ has to be arranged and the order of the decreasing bond energy the same or the reverse order has to be explained.

Concept Introduction:

Bond length: It is defined as the average distance between nuclei of two bonded atoms in a molecule is called bond length.

The bond energy is directly proportional to the bond order and inversely proportional to the length.  The number of bonds increases the bond energy also increases.

The order of bond lengths is given as,

Triple bond < Double bond < Single bond
