Chapter 14.5, Problem 14.19P

Interpretation Introduction

Interpretation:

Functional groups present in aspartame has to be identified.

Concept Introduction:

Functional group is an atom or a group of atoms that is present in a compound which is responsible for the physical and chemical properties of the compound.

Functional group is an atom or a group of atoms that is present in a compound which is responsible for the physical and chemical properties of the compound.  Carbonyl carbon bonded to a hydroxyl group is known as carboxylic acid.  Carbonyl carbon bonded to an alkoxy is known as ester.  Carbonyl carbon bonded to a nitrogen atom is known as amide.

Amines are compounds that contains carbon atom bonded to nitrogen in ammonia by replacing one or more hydrogen atoms.  Primary amine is the one, which has only one carbon atom and two hydrogen atoms bonded to the nitrogen atom.  General structure of primary amine is ${\text{RNH}}_{\text{2}}$.  Secondary amine is the one, which has two carbon atoms and one hydrogen atom bonded to the nitrogen atom.  General structure of secondary amine is ${\text{R}}_{\text{2}}\text{NH}$.  Tertiary amine is the one, which has three carbon atoms bonded to the nitrogen atom.  General structure of tertiary amine is ${\text{R}}_{\text{3}}\text{N}$.
