Question

Is silk a synthetic polymer?

Answer 1

Hint: Macromolecules known as polymers are created by joining a lot of tiny molecules together. Strong covalent connections bind the repeating units together in polymers. Monomers are small molecules that join to create polymer molecules. The polymerization process, which is used to create synthetic polymers, is the method of creating the polymer.

Complete Step by Step Solution:
Based primarily on their physical and chemical characteristics, polymers are divided into numerous categories. In fact,

• • Based on source

• Based on monomers

• Based on polymerization

• Based on functionality

• Based on intermolecular forces

• Based on structure

Based on source: Based on the presence of an abundant source in nature, polymers are divided into two categories. These are both manmade and natural polymers.
(1) Natural polymers: either plants or animals are used to obtain these. cellulose, jute, linen, silk, etc. are a few examples.
(2) Synthetic polymers: Examples of man-made polymers manufactured in daily life as well as in industry or laboratories include plastic, synthetic fibres, and synthetic rubbers. The polymerization method is used to create these artificial polymers. For example, PVC, Teflon, Terylene, etc.

Thus, jute, linen, and silk are examples of natural polymers, while Terylene is a synthetic polymer.

Note: The two-step mechanism reaction is the Sandmeyer reaction. The free radical mechanism is used in the Sandmeyer reaction. The halogen linked to the copper enters the benzene ring during this process.
