Chapter 13: Problem 4

The three different bond orders correspond to designations of single, double, and triple bonds. What is the relationship between the bond order of a bond and the designation of single, double, and triple bonds?

Short Answer

Expert verified
The bond order is directly related to whether a bond is denoted as single, double, or triple. Specifically, a single bond corresponds to a bond order of 1, a double bond to a bond order of 2, and a triple bond to a bond order of 3. Thus, the higher the bond order, the stronger and shorter the bond.

Step by step solution

01

Understanding Bond Order

Bond order is the number of chemical bonds between a pair of atoms; in molecules, it is a measure of the bond strength and is often expressed in terms of a single, double, or triple bond.
02

Defining Single, Double, and Triple Bonds

A single bond has a bond order of 1 and is represented by a single line between two atoms in chemical structure diagrams. A double bond has a bond order of 2 and is depicted by two lines, while a triple bond has a bond order of 3 and is depicted by three lines.
03

Relating Bond Order and Designations

In essence, the bond order relates directly to the designation of a bond as single, double, or triple. Each type stands for bond orders of 1, 2, and 3 respectively. The higher the bond order, the stronger and shorter the bond.
