Chapter 12, Problem 68P

(a)

Interpretation Introduction

Interpretation:The functional groups present in albuterol should be determined.

Concept Introduction: A group of atoms or an atom that is responsible for the characteristic reactions of a particular compound is said to be the functional group. Every functional group shows distinctive chemical properties irrespective of the moiety to which it is attached.

(b)

Interpretation Introduction

Interpretation:The structural formula of the product formed by reacting albuterol with one equivalent of sodium hydroxide should be drawn.

Concept Introduction: A compound that can donate proton ( ${\text{H}}^{+}$ ) is said to be acid. Phenols after losing a proton forms phenoxide ion which is stabilized as the negative charge on oxygen atom is delocalised around the benzene ring.

(c)

Interpretation Introduction

Interpretation: The structural formula of the product formed by reacting albuterol with one equivalent of hydrochloric acid should be drawn.

Concept Introduction: Hydrochloric acids reacts with bases and forms salts. In albuterol, secondary amines act as a base and produces salts on reacting with acids like hydrochloric acid.
