Chapter 1, Problem 1.42AP

Interpretation Introduction

(a)

Interpretation:

The dihedral angle that can be ruled out by the fact that ${\text{H}}_{\text{2}}{\text{O}}_{\text{2}}$ has a large dipole moment $\left(2.13\text{D}\right)$ is to be stated.

Concept introduction:

The quantity that is used to measure the uneven distribution of electrons around the atoms of a compound that possess the covalent bonds is known as dipole moment. It is denoted by $\mu$.

The angle between the two intersecting planes is known as dihedral angle. It is also described as the angle between the planes passing through two sets of three atoms. There should be two atoms in common. It is also known as the torsion angle.

Interpretation Introduction

(b)

Interpretation:

The preferred dihedral angle in ${\text{H}}_{\text{2}}{\text{O}}_{\text{2}}$ by using the bond dipole moment of the $\text{O}-\text{H}$ bond as $1.52\text{D}$ and the overall dipole moment of ${\text{H}}_{\text{2}}{\text{O}}_{\text{2}}$ is to be stated.
