Chapter 10: Problem 48

Explain the significance of bond order. Can bond order be used for quantitative comparisons of the strengths of chemical bonds?

Short Answer

Expert verified
Bond Order is the number of chemical bonds between two atoms. It indicates the stability of a bond or molecule, and a higher bond order typically signifies a stronger bond. Yes, bond order can provide a rough estimate for comparing the strengths of different chemical bonds, although other factors should also be considered.

Step by step solution

01

Explanation of Bond Order

Bond Order refers to the number of chemical bonds between a pair of atoms. In simple terms, it tells us about the stability of a bond or molecule. For instance, a bond order of 1 corresponds to a 'single bond', 2 to a 'double bond', and 3 to a 'triple bond'.
02

Relating Bond Order and Bond Strength

Generally, the larger the bond order, the stronger the chemical bond. A triple bond is stronger than a double bond, and a double bond is stronger than a single bond. This is because as the bond order increases, more electrons are involved in bond formation, leading to a stronger electrostatic attraction between atoms.
03

Application for Bond Strength Comparison

Yes, bond order can be used for quantitative comparisons of the strengths of chemical bonds. It can serve as a rough estimate for comparing which bond is stronger or weaker. However, it should be noted that bond strength may also depend on other factors such as the atomic radii, electron affinity, electronegativity, and the spatial orientation of the bonding orbitals.
