Chapter 3, Problem 3.28P

Interpretation Introduction

(a)

Interpretation: The functional groups present in aspartame are to be identified.

Concept introduction: An atom or a group of atoms which are responsible for characteristic physical and chemical properties of the compound are collectively known as functional groups. The functional groups are the most reactive part present in the molecule.

Interpretation Introduction

(b)

Interpretation: The sites that can hydrogen bond to the oxygen atom of water are to be labeled.

Concept introduction: A partially positively charged hydrogen atom covalently bonded to electronegative atom $\text{(O,}\text{F,}\text{N)}$ is attracted to lone pair of electrons present on another electronegative atom $\text{(O,}\text{F,}\text{N)}$ exhibit hydrogen bonding.

Interpretation Introduction

(c)

Interpretation: The sites that can hydrogen bond with hydrogen atom of water are to be labeled.

Concept introduction: A partially positively charged hydrogen atom covalently bonded to electronegative atom $\text{(O,}\text{F,}\text{N)}$ is attracted to lone pair of electrons present on another electronegative atom $\text{(O,}\text{F,}\text{N)}$ exhibit hydrogen bonding.
