Chapter 22.3, Problem 21LC

Interpretation Introduction

Interpretation: Two constitutional isomers have different properties such as boiling point needs to be explained.

Concept Introduction: Constitutional isomers share the same molecular formula but have different bonding patterns and atomic organization.

Explanation of Solution

The two constitutional isomers have different boiling points depending on the type of carbon chain and the groups attached.

For example, ketones and aldehydes are constitutional isomers.

In carbonyl groups, ketones have higher boiling as compared to isomeric aldehydes due to the presence of 2 electrons releasing alkyl groups around the carbonyl carbon that makes them more polar.
