Chapter 9, Problem 121IE

(a)

Interpretation Introduction

To determine: The coordinate axis system in which y- axis is in vertical and x-axis is in horizontal in the plane of paper.

(b)

Interpretation Introduction

To determine: The Lewis structure of $\text{CO}$ on the x axis with carbon atom near to the metal atom.

(c)

Interpretation Introduction

To determine: The diagram of ${\text{π}}_{2\text{p}}^{*}$ orbital of $\text{CO}$ atom pointing toward M in the coordinate axis.

(d)

Interpretation Introduction

To determine: The diagram of ${\text{d}}_{xy}$ orbital of metal M on the given coordinate axis; also if it overlap with the ${\text{π}}_{2\text{p}}^{*}$ of $\text{CO}$ or not.

(e)

Interpretation Introduction

To determine: If the bond between metal and carbon atom is $\text{σ}$ or $\text{π}$ .

(f)

Interpretation Introduction

To determine: The comparison of the strength of $\text{CO}$ bond in the complex and $\text{CO}$ alone.
