Chapter 14.1, Problem 2RQ

Interpretation Introduction

Interpretation: Whether hydrogen bond is a true chemical bond or not is be explained.

Concept introduction: A hydrogen bond is formed between a hydrogen atom of one molecule an electronegative atom such as oxygen, nitrogen and fluorine of other atom. It is a inter-molecular force whereas a chemical bond is formed between atoms of the same molecule making it an intra-molecular force.

Answer to Problem 2RQ

Hydrogen bond is not a true chemical bond.

Explanation of Solution

A true chemical bond is the one that is formed between atoms of the same molecule resulting in the formation of chemical compounds. It is an intra-molecular force existing in molecules of the compounds whereas hydrogen bond is a dipole-dipole bond affecting the physical state of the substance. Also it is an inter-molecular force unlike a chemical bond.

Conclusion

Hydrogen bond is an inter-molecular force whereas a chemical bond is an intra-molecular bond. Hence, hydrogen bond is not a true chemical bond.
