For example, nylon 6, 6 is formed by condensation polymerization of hexamethylenediamine and adipic acid. Proteins are formed from amino acids which may be linked in different ways. For example Nylon 6, 6 is a condensation polymerisation of adipic acid and hexamethylene diamine. Class. It is a chapter which is purely conceptual with a lot of emphasis in theory. Answer: Explaination: (b) and (c). Condensation polymerization is the process of formation of polymers by repeated condensation reactions between two different bi-functional or tri-functional monomers. For example, nylon 6, 6 is formed by condensation polymerization of hexamethylenediamine and adipic acid. Polymers have a high molecular mass usually ranging between 103−107 u. THERMOSETTING RESINS. double or triple bonds to form polymers. Draw the repeating unit for a condensation polymer. Get NCERT Exemplar Solutions for Class 12 Chapter Polymers here. Polymer is defined as a chemical substance of a high molecular mass formed by the combination of a large number of simple molecules, called monomers. A few common examples are starch, cellulose, proteins, rubber nucleic acids, etc. What are polymers? Some examples are ethene, vinyl chloride, acrylonitrile, phenol and formaldehyde etc. A small molecule such as water or hydrochloric acid is eliminated in each condensation. • Each monomer has two of the same functional groups. Among them, starch and cellulose are the polymers of glucose molecules. Eg: propene, ethene, vinyl chloride, styrene. Which of the following polymers of glucose is stored by animals? What is polymerisation? A small molecule such as water or hydrochloric acid is eliminated in each condensation. These are formed by the condensation of two or more monomers with the elimination of simple molecules like H2O, NH3, ROH, etc. Simple, reactive molecules known as monomers, combine with each other in large numbers through covalent bonds to give rise to polymers. What is a homo-polymer?

Examples – Nylon 6, 6, Nylon 6. Q2: Explain natural and synthetic polymers with the help of two examples of each type? • When these monomers react, small molecules such as water are lost 2. A small molecule such as water or hydrochloric acid is eliminated in each condensation. Dacron and Novolac are condensation polymers. Polymers have a high molecular mass (103 − 107 u).

Condensation polymerization is the process of formation of polymers by repeated condensation reactions between two different bi-functional or tri-functional monomers. take place. • Condensation polymers are made from two different monomers. Condensation Polymer:-The condensation polymers are formed by repeated condensation reaction between two different bi-functional or tri-functional monomeric units. Some examples are polythene, nylon-66, bakelite, rubber, etc. Condensation polymer: Simple monomer units combine together to form polymer followed by the removal of small molecules like H 2 O, NH 3 etc. Class 12 Chemistry Polymers NCERT solutions are handy for students in many ways. A small molecule such as water or hydrochloric acid is eliminated in each condensation. II. This chapter explains the terms monomer, polymer and polymerisation and encourages you to identify the applications of the same in daily life. Check you answers with answer keys provided. Multiple Choice Questions (Type-I) NCERT … Condensation polymers: ... Below is an example of the formation of Nylon 66, a common polymeric clothing material, involving one each of two monomers, hexamethylenediamine, and adipic acid, reacting to form a dimer of Nylon 66. How is Nylon – 6, 6 different from Nylon -6? Some examples of common condensation polymers are polyacetals, proteins, and polyamides. Condensation polymerization is the process of formation of polymers by repeated condensation reactions between two different bi-functional or tri-functional monomers. Polymers can be natural as well as synthetic. Answer: Polymerisation is the process of formation of polymers from respective monomers, Homopolymers are polymers formed by the … For example, nylon 6, 6 is formed by condensation polymerization of hexamethylenediamine and adipic acid. Practice to excel and get familiar with the paper pattern and the type of questions. Condensation polymerization is the process of formation of polymers by repeated condensation reactions between two different bi-functional or tri-functional monomers. Buna-S needs buta 1, 3-diene and Neoprene needs 2-chloro 1,3-butadiene. Chemistry . In a polymer, various … In a polymer, various monomer units are joined by strong covalent bonds. NCERT Class 12 Chemistry Chapter 15 is for Polymers. One example of a condensation polymer is Nylon 6,6. simple and reactive molecules from which the polymers are prepared either by addition or condensation polymerisation. Single Correct Answer Type. Natural polymers: The polymers which occur in nature mostly in plants and animals are called natural polymers. Natural polymers: The polymers which occur in nature mostly in plants and animals are called natural polymers. Therefore it is also called step growth polymerisation. Google Will End Support to Google Keep Chrome App by Feb 2021 ; AWS Launches its Next-gen GPU Instances Powered by … Here we have given NCERT Exemplar Class 12 Chemistry Chapter 15 Polymers.
