Question

Bakelite is an example of:
A.Elastomer
B.Fibre
C.Thermoplastic
D.Thermosetting polymer

Answer 1

Hint: First we should be aware of the term bakelite which is a kind of polymer. Then we can give the nature of the polymer and its constituents also that are, phenol and formaldehyde. Now after the process of formation we get the nature thus the type of polymer it represents, which is Thermosetting polymer.

Complete Step by step answer: Here in the given question statement the question is regarding the polymer called bakelite. Now we have to give the basic idea of the polymer along with its constituents and the basic definition so that we can get what kind of polymer is it. As the given options signifies kinds of polymer. A kind of polymer depends upon the process used to make the polymer.
Now here is the step by step answer to the question:
Bakelite is a material which is a polymer. It is an example of a thermosetting polymer.
Apart from that it is also a type of phenol-formaldehyde polymer. It is a special kind of polymer.
This is among the polymers that are obtained by the process of condensation reaction. The reaction takes place between the phenol and formaldehyde, and in the presence of either an acid or a base catalyst.
Apart from that the reaction starts with the initial formation of o− and/or p−hydroxymethyl phenols derivatives. But after the reaction proceeds further, it reacts with the phenol in order to form compounds having rings. These are joined to each other through multiple \[-C{H_2}\] groups.

So that provides us the correct option as option D, Thermosetting Polymer.

Note: Bakelite was designated a National Historic Chemical Landmark on November $9$ , \[1993\] , by the American Chemical Society in recognition of its significance as the world's first synthetic plastic. In recent years the "retro" appeal of old Bakelite products has made them collectible.
