Chapter 22.3, Problem 24LC

Interpretation Introduction

Interpretation: Constitutional isomers and Stereoisomers are similar as well as different needs to be explained.

Concept Introduction: Compounds which have the same chemical formula but the properties and arrangement of atoms in the molecule are different are called Isomers.

Answer to Problem 24LC

Molecules having the same molecular formula but differing in the atomic arrangement are Constitutional isomers and molecules having the same formula as well as the same atomic arrangement but differ in the spatial arrangement are Stereoisomers.

Explanation of Solution

Given Information: Constitutional isomers and Stereoisomers are the same as well as different.

Molecules having the same molecular formula but differing in atomic arrangements are Constitutional isomers whereas molecules having the same formula as well as the same atomic arrangement but differing in the spatial arrangement are Stereoisomers.

In Constitutional isomers, the arrangement of atoms differs from one another whereas, in Stereoisomers, the arrangement remains the same.

Chirality is absent in Constitutional isomers and present in Stereoisomers.

Constitutional isomers have different physical and chemical properties whereas Stereoisomers have relatively close physical and chemical properties.

Conclusion

Molecules having the same molecular formula but differing in the atomic arrangement are Constitutional isomers and molecules having the same formula as well as the same atomic arrangement but differ in the spatial arrangement are Stereoisomers.
