Chapter 3, Problem 3.9P

Interpretation Introduction

(a)

Interpretation:

The acid, base and conjugate acid-base pairs for ${\ddot{N}\text{H}}_{\text{3}}{+}^{-}\text{:}\underset{¨}{\ddot{O}}\text{H}{⥄}^{-}\text{:}{\ddot{N}\text{H}}_2+{\text{H}}_{\text{2}}\ddot{O}\text{:}$ reaction are to be predicted. The curved-arrow notation for the reaction in the left-to-right direction is to be drawn.

Concept introduction:

The displacement of a pair of electrons from an atom by the donation of electrons from another atom is known as electron-pair displacement reaction. The curved-arrow notation is used to indicate the displaced and donated electron pair from an atom.

Interpretation Introduction

(b)

Interpretation:

The acid, base and conjugate acid-base pairs for ${\ddot{N}\text{H}}_3+{\ddot{N}\text{H}}_3{⥄}^{-}\text{:}{\ddot{N}\text{H}}_2+\stackrel{+}{\text{N}}{\text{H}}_{\text{4}}$ reaction are to be predicted. The curved-arrow notation for the reaction in the left-to-right direction is to be drawn.
