Chapter U2.1, Problem 2E

Interpretation Introduction

Interpretation:

The molecular formulas and chemical names related to smell, evidence on this concept needs to be identified.

Concept Introduction :

The smell is due to one or more volatilized chemical compounds which are usually present in low concentrations that animals and humans can notice by their senses.

Explanation of Solution

Molecular formulas are related with smell because it shows the type of atoms present in the molecule. The chemical formula helps to determine the functional groups in the molecule.

Different functional groups have different smells. For example: ester has a fruity smell, carboxylic acid has a putrid smell, ketone has minty smell and amines have fishy smell.

Thus, from the chemical formula by determining the functional groups, smell of the molecule can be identified.
