Chapter 11, Problem 11.43P

(a)

Interpretation Introduction

Interpretation:

The Lewis structure of ${\text{N}}_2{\text{H}}_4$ and ${\text{CS}}_2$ is to be drawn.

Concept introduction:

The Lewis structures are the diagrams that are used to show the bonding between various atoms in a covalent molecule and the number of lone pairs present in that molecule. These are also known as Lewis dot diagrams, electron dot diagrams, Lewis dot structures or Lewis dot formula. These are used to predict the geometry, polarity, and reactivity of covalent compounds.

(b)

Interpretation Introduction

Interpretation:

The change in electron-group arrangement, molecular shape and hybridization of nitrogen when hydrazine reacts to form the given product is to be determined.

Concept introduction:

Hybridization is the process of intermixing of atomic orbital of slightly different energies to form hybrid orbitals that have similar energy. These orbital have lower energy and more stability than the atomic orbital.

The molecular shape is the three-dimensional arrangement of atoms in the molecule. It depends on the bond pairs as well as lone pairs. The electron-group arrangement tells about the distribution of electrons around the various atoms in the molecule.

(c)

Interpretation Introduction

Interpretation:

The change in electron-group arrangement, molecular shape and hybridization of carbon when carbon disulfide reacts to form the given product is to be determined.
