Chapter U2.28, Problem 1E

Interpretation Introduction

Interpretation: This is to be explained how smells are classified and the purpose of it needs to be explained.

Concept Introduction:

The functional groups are defined as the structural features common in groups of molecules. It is a unique property of a molecule.

Explanation of Solution

The properties of compounds depend on the functional group present in them therefore; compounds with same functional groups have similar chemical properties. The name of the compound also depends on the functional groups it contains. Also, different functional groups have different smells. For examples, the compounds containing ester functional groups are generally sweet in smell; compounds with carboxylic acid functional groups have putrid smell. Therefore, to determine the functional group of any substance, it is very important to predict the smell of the compound.

Conclusion

Thus, smells are classified according to functional groups present in the compounds. The purpose of this classification is determining the functional groups in a compound.
