Chapter 22.2, Problem 9SSC

Interpretation Introduction

Interpretation:

The two elements commonly found in functional groups needs to be identified.

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.

Answer to Problem 9SSC

Oxygen and hydrogen.

Explanation of Solution

The functional group is a specific group of bonds and atoms in an organic compound which determines the chemical properties and physical properties of the compound. Two compounds with same functional groups will behave in a similar way and show similar reactions.

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.

Thus, the two elements which are generally present in functional groups are oxygen and hydrogen elements.

Conclusion

Thus, the two elements in functional groups are oxygen and hydrogen.
