Chapter 22, Problem 11STP

Interpretation Introduction

Interpretation:

The substituted hydrocarbon with general formula R-OH 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 11STP

Correct Answer: Option (a) is correct.

Explanation of Solution

Reason for correct options:

The given general formula is R-OH.

Here, the functional group is −OH which is a hydroxyl group. Thus, the given substituted hydrocarbon is an alcohol.

The correct option is (a).

Conclusion

Reason for incorrect options:

The general formula for amine is R-NH2, ketone is R-CO-R’ and carboxylic acid is R-COOH. Thus, options (b), (c) and (d) are incorrect.
