Question

Definition Definition Organic compounds that have a carbonyl group, C=O, as their functional group. The carbonyl group in aldehydes is placed at the end of the molecular structure, which means the C=O is attached to one hydrogen atom and an alkyl group or a benzene ring. Just like all the other homologous series in organic chemistry, the naming of aldehydes uses the suffix “-al”. The general molecular formula is C n H 2n O.

Chapter 22.3, Problem 17SSC

Interpretation Introduction

Interpretation:

The reason for water soluble carboxyl groups to show acidic properties in solutions but not this is not the case with aldehyde needs to be explained.

Concept introduction:

The functional group is the group present on the main carbon chain of an organic compound. It determines the chemical properties and the type of reactions an organic compound can show.

Expert Solution & Answer

Explanation of Solution

The structural formula of an organic compound containing carboxyl groups and aldehyde is as follows:

Chemistry: Matter and Change, Chapter 22.3, Problem 17SSC , additional homework tip 1

Here, carboxyl group can show hydrogen bonding with water due to H atom in −COOH group attached to O atom.

This hydrogen atom is ionizable and can show following reaction:

Chemistry: Matter and Change, Chapter 22.3, Problem 17SSC , additional homework tip 3

Thus, the carboxyl group in organic compound is acidic in nature.

There is no ionizable H atom in aldehyde group therefore; it does not show any acidic property.
