Chapter 13, Problem 13.85AP

(a)

Interpretation Introduction

Interpretation:

Acid-base reaction that takes place between ${\text{CH}}_{\text{3}}{\text{CH}}_{\text{2}}{\text{NH}}_{\text{2}}$ and water has to be drawn.

Concept Introduction:

Amines are basic in nature.  Water is an amphoteric substance.  Thus it donates a proton to the amine resulting in formation of ammonium salt.  The counter ion present is the hydroxide ion from water molecule.

(b)

Interpretation Introduction

Interpretation:

Acid-base reaction that takes place between ${{\text{(CH}}_{\text{3}}{\text{CH}}_{\text{2}}\text{)}}_{\text{2}}\text{NH}$ and water has to be drawn.

Concept Introduction:

Refer part (a).

(c)

Interpretation Introduction

Interpretation:

Acid-base reaction that takes place between ${{\text{(CH}}_{\text{3}}{\text{CH}}_{\text{2}}\text{)}}_{\text{3}}\text{N}$ and water has to be drawn.
