Q86P - Chemistry: Molecular Nature Of Matter And Change

Question

Show two chains of three units of each of a sheet silicon polymer made from $\mathbf{(}\mathbf{C}{\mathbf{H}}_{\mathbf{3}}{\mathbf{)}}_{\mathbf{2}}\mathbf{Si}{\left(\mathbf{OH}\right)}_{\mathbf{2}}$ with $\mathbf{(}\mathbf{C}{\mathbf{H}}_{\mathbf{3}}{\mathbf{)}}_{\mathbf{2}}\mathbf{Si}{\left(\mathbf{OH}\right)}_{\mathbf{3}}$ added to crosslink the chains.

Step-by-Step Solution

Answer

Silicon polymers are also called polysiloxanes. These are synthetic polymers where the backbone is Silicon-oxygen. 

Introduction

Silicon polymers are also called polysiloxanes. These are synthetic polymers where the backbone is silicon-oxygen. Here organic groups are also attached to the silicon atom making a C-Si bond, where the organic group is exposed to the outside. The simplest silicone is silane . If oxygen is also present, they’re called siloxanes.

General structure of silicones

The silicones which are used vastly are those having methyl groups in the backbone. The general structure of these sillicones can be represented as- 

Structure

The given silicone polymers will make a three-dimensional cross-linked structure which can be shown as
