Chapter 22, Problem 67A

Interpretation Introduction

(a)

Interpretation:

The functional groups present in levadopa 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.

Explanation of Solution

The given compound is as follows:

From the above structure, it can be seen that it has 3 different functional groups namely hydroxyl group −OH), amino group (-NH₂)and carboxylic acid group (-COOH).

The functional groups are labelled in the structure as follows:
