Chapter U2.33, Problem 2E

Interpretation Introduction

Interpretation:

The information that is required to figure out the smell of a compound must be explained.

Concept introduction:

Different compounds have different structural features and so different smell. Different functional groups have different bonding interaction with receptor of nasal cavities.

Answer to Problem 2E

The structural features particularly the functional groups must be known to figure out the smell of a compound.

Explanation of Solution

To know about the smell of a compound the functional groups must be known. The functional groups are atoms or group of atoms which controls the physical and chemical properties of a compound Remaining part of the molecule has less influence in the physical and chemical properties of a compound. For example, ester has fruity smell, carboxylic compounds are putrid, alcoholic compounds have pungent odor and ketone have minty smell. Thus, the smell depends on functional groups present in the molecule.

Conclusion

Functional groups of a compound must be known to figure out the smell of a compound.
