Chapter 9, Problem 9B.1BST

(a)

Interpretation Introduction

Interpretation:

The type of reaction in which formation nickel tetra carbonyl has taken place has to be given.

Concept Introduction:

Redox Reaction:

An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species.  An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.

Acid- Base reaction:

Acid–base reaction is a type of chemical process typified by the exchange of one or more hydrogen ions $\left({\text{H}}^{\text{+}}\right)$ between species that may be neutral, (such as water, ${\text{H}}_{\text{2}}\text{O}$ or acetic acid ${\text{CH}}_{\text{3}}{\text{CO}}_{\text{2}}\text{H}$ ) or electrically charged (ions, such as ammonium, ${\text{NH}}_{\text{4}}{}^{\text{+}}$ hydroxide, ${\text{OH}}^{\text{-}}$ or carbonate, ${\text{(CO}}_{\text{3}}{}^{\text{2-}}\text{)}\text{.}$

(b)

Interpretation Introduction

Interpretation:

The acid and base in the reaction has to be given.

Concept Introduction:

• A Lewis acid is any substance, such as the ${\text{H}}^{\text{+}}$ ion, that can accept a pair of nonbonding electrons.  In other words, a Lewis acid is an electron-pair acceptor.
• A Lewis base is any substance, such as the ${\text{OH}}^{\text{-}}$ ion, that can donate a pair of nonbonding electrons.  A Lewis base is therefore an electron-pair donor.
