Chapter 12, Problem 55A

Interpretation Introduction

Interpretation:

The term bond energy is to be explained.

Concept introduction:

Bond energy is related to strength of the bond formed between the atoms.

Stronger the bond, more is the bond energy.

Answer to Problem 55A

Bond energy of a chemical bond is energy required to break the bond. It is expressed in $\mathrm{k}\mathrm{J}/\mathrm{m}\mathrm{o}\mathrm{l}$ .

Explanation of Solution

• Bond energy of triple bond is more than double bond and double bond is more than single bond because triple bond is stronger than double bond and double bond is stronger than single bond.
• The bond having more s-character has more bond energy.
• More the polarity of bond, lesser is the bond energy.

Conclusion

Thus, bond energy gives the stability of bond.
