An example of biopolymer is: 
Therefore, the correct answer is DNA.
Bakelite is prepared by the reaction between: 
Phenol and formaldehyde undergo condensation polymerization under two different conditions to give a cross-linked polymer called Bakelite.
Reaction Mechanism for preparation of Bakelite:
In elastomer, intermolecular forces are: 
Nylon 66 is a polyamide obtained by the reaction of: 
Therefore, the correct answer is B.
Which one of the following is used to make "nonstick" cook-wares? 
We know that polytetrafluoroethylene or Teflon is a tough material, resistant to heat, and a bad conductor of electricity.
Thus, it is used for coating the cookware to make them non-sticky.
Natural rubber is a polymer of: 
Natural rubber is a polymer of isoprene, [CH2 =C(CH3)CH=CH2] i.e. 2-methylbutadiene
CF2 = CF2 is a unit of: 
CF2 = CF2 is a unit of Teflon.
Which of the following is not correctly matched?
Terylene is prepared by condensing dimethyl terephthalate and ethylene glycol in presence of a weak base, (calcium acetate). Methanol is eliminated during condensation.
Monomer of : 
2-methylpropene is the monomer of
Vitamin B12 contains: 
Acrilan is a hard, stimulated and a high melting material. Which of the following represents its structure ? 
Acrylon is also called as orlon or polyacrylonitrile and is formed by the given reaction.
Which one of the following monomers gives the polymer neoprene on polymerization? 
Chloroprene or 2-chloro-1,3-butadiene on addition polymerisation gives neoprene.
Which one of the following is a chain-growth polymer? 
The monomer of the polymer: 
Addition of monomers follows isoprene rule.
The given compound is a co-polymer of hexamethylene diamine and adipic acid. It is actually Nylon-6,6.
Additional Information: A co-polymer is a polymer that is made up of two or more monomer species. Many commercially important polymers are copolymers. Examples include polyethylene-vinyl acetate (PEVA), nitrile rubber, and acrylonitrile butadiene styrene (ABS).
Which one of the following polymers is prepared by condensation polymerisation? 
Which one of the following statements is not true? 
The natural rubber has a 'cis' configuration at every double bond. It is a linear 1,4 polymer of isoprene. In other words, natural rubber is cis-polyisoprene.
Therefore, All statements except (b) are correct
Structures of some common polymers are given. Which one is not correctly presented? 
Neoprene is a polymer of chloroprene.
Hence, The correct representation will be:
Which of the following structures represents neoprene polymer?

Of the following which one is classified as polyester polymer? 
Polyesters are condensation polymers of diabasic acid and diol.
Which one of the following is not a condensation polymer ? 
Neoprene is an addition polymer of isoprene.
Which of the following statements is false? 
Nylon-66 is an example of the first synthetic fibers produced from simple molecules. It is prepared by condensation polymerization of adipic acid and hexamethylenediamine.
Which one of the following sets forms the biodegradable polymer? [2012 M]
Biodegradable polymer is Nylon-2- Nylon-6 which is copolymer of glycine (H2N – CH2– COOH) and amino caproic acid (H2N–(CH2)5 – COOH).
Which is the monomer of Neoprene in the following? [NEET 2013]
Chloroprene is the monomer of neoprene.
