Which functional group is characteristic of carboxylic acids?a. -OHb. -CHOc. -COOHd. -NH2

Break Down the Problem

1. Identify the functional groups listed in the options.
2. Determine which functional group is specifically associated with carboxylic acids.

Relevant Concepts

• Functional groups are specific groups of atoms within molecules that are responsible for the characteristic chemical reactions of those molecules.
• Carboxylic acids are organic compounds that contain a carboxyl group (-COOH).

Analysis and Detail

1. -OH: This is the hydroxyl group, characteristic of alcohols.
2. -CHO: This is the aldehyde group, found in aldehydes.
3. -COOH: This is the carboxyl group, which defines carboxylic acids.
4. -NH2: This is the amino group, often found in amines and amino acids.

Among the provided options, the carboxyl group (-COOH) is the correct one associated with carboxylic acids.

Verify and Summarize

After analyzing all the given options and their characteristics, it is clear that the carboxylic acids are defined by the presence of the carboxyl functional group.

Final Answer

The functional group characteristic of carboxylic acids is c. -COOH.
