Chapter 11, Problem 11.34P

(a)

Interpretation Introduction

Interpretation:

The stability of ${\text{Be}}_2{}^{+}$ on the basis of the molecular orbital diagram is to be determined.

Concept introduction:

A molecular orbital diagram is a tool that is used to describe the chemical bonding formed between different molecules. It is used to predict the bond strength and the electronic transitions that a molecule can undergo.

(b)

Interpretation Introduction

Interpretation:

Whether ${\text{Be}}_2{}^{+}$ is diamagnetic or not on the basis of the molecular orbital diagram is to be identified.

Concept introduction:

A molecular orbital diagram is a tool that is used to describe the chemical bonding formed between different molecules. It is used to predict the bond strength and the electronic transitions that a molecule can undergo.

Diamagnetism is the property of substance due to which they are repelled by the external magnetic field. It arises due to the presence of paired electrons in the molecule.

(c)

Interpretation Introduction

Interpretation:

The outer electron configuration of ${\text{Be}}_2{}^{+}$ on the basis of the molecular orbital diagram is to be determined.

Concept introduction:

A molecular orbital diagram is a tool that is used to describe the chemical bonding formed between different molecules. It is used to predict the bond strength and the electronic transitions that a molecule can undergo.

The outer electron configuration tells about the distribution of electrons in the outermost shell of the atom. It is used to predict the physical and chemical properties of the molecule.
