Chapter 22, Problem 12STP

Interpretation Introduction

Interpretation:

The functional group in the given compound needs to be determined.

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. The name of the group depends on the atoms present in the group for example an −OH group contains O and H atom thus, it is a hydroxyl group. The different functional groups are named according to IUPAC rule.

Name of some functional groups are: -OH: alcohol, -CHO: aldehyde, -COOH: carboxylic acid etc.

Answer to Problem 12STP

Carboxylic group.

Explanation of Solution

The given compound is as follows:

The given general formula is R-COOH.

Here, the functional group is −COOH which is a carboxyl group. Thus, the given substituted hydrocarbon is a carboxylic acid.

Conclusion

Therefore, the functional group present in the compound is carboxylic group.
