Question

Which one of the following polymers is not properly matched to its monomer?
(A) Orion acrylonitrile
(B) Synthetic rubber- 2 chloro1, 3diene
(C) nylon- adipic acid hexamethylenediamine
(D)Teflon-vinyl chloride

Answer 1

Hint :Polymers are high molecular masses containing molecules which form repeating structure units known as monomers. Monomers are low molecular masses containing molecules which form repeating structure units of polymer.

Complete Step By Step Answer:
The process of formation of polymers from their respective monomers is known as polymerisation. The polymer are two types on the basis of number of monomer from polymer-
 $ \left( 1 \right) $ Homo polymer- The polymer made by only one type of monomer is known as homo polymer. Example of homo polymer polystyrene is made of only one type of monomer that is styrene.
 $ \left( 2 \right) $ Copolymer- The polymer made from more than one type of monomer is known as homo polymer. Example of copolymer is Buna S is made by buta1, 3 dine.
So Orion is an example of a homo polymer made by acrylonitrile.
Synthetic rubber is also an example of homo polymer that is made by-2 chloro1, 3diene.
Nylon is an example of copolymer that is made by adipic acid hexamethylenediamine.
Teflon is an example of homo polymer that is made by tetra fluoro ethylene.
Hence option D is the correct option. Teflon is not made of vinyl chloride. $ (C{F_2} = C{F_2}) $ .

Note :
Polymer are different type on the basis of source -
 $ \left( 1 \right) $ Natural polymer The polymer is obtained by plants and animals examples of homo polymer are starch, cellulose.
  $ \left( 2 \right) $ semi-synthetic polymer – semi- synthetic polymer are obtained from nature but chemically modified in lab examples of semi-synthetic polymer are cellulose diacetate , vulcanised rubber.
 $ \left( 3 \right) $ Synthetic polymer: synthetic polymers are made by human beings in lab examples of synthetic polymers are polythene, nylon, Bakelite.
Teflon is prepared by tetra fluoro ethylene at high pressure in the presence of peroxide.
Teflon is used in making non-stick utensils because Teflon is stable at high temperature.
