Chapter 17, Problem 17.95P

Interpretation Introduction

(a)

Interpretation:

The reaction that occurs when naproxen is treated with NaOH should be determined.

Concept Introduction:

Functional groups are the groups of atoms or atoms which are bonded with parent carbon chain in the organic molecule and are responsible for the physical and chemical properties of the compound. In organic chemistry, there are different functional groups such as carboxylic acid, alcohol, ester, or amide.

Interpretation Introduction

(b)

Interpretation:

The form of naproxen that exists in stomach should be determined.

Concept Introduction:

An acid is a substance that gives ${\text{H}}^{\text{+}}$ ions in its solution whereas a basic substance gives ${\text{OH}}^{\text{-}}$ ions in its solution. The reaction of an acid HA with a base BOH can be written as:

  $\text{HA + BOH}\text{}\underset{}{\to }{\text{ BA + H}}_{\text{2}}\text{O}$

Here BA stands for salt and the reaction named as neutralization reaction. Thus the reaction of an acid with a base results in the formation of salt and water. The salt is an ionic compound that is formed by the combination of the cation ( ${\text{B}}^{\text{+}}$ ) from base and anion ( ${\text{A}}^{\text{-}}$ ) from acid and forms salt BA.

(c)

Interpretation:

The form of naproxen that exists in intestine should be determined.
