Question

write names of monomers for the following polymers
polyethene
cellulose
bakelite
nylon​

Answer 1

answer ;

i)Bakelite

Bakelite is a condensation polymer of phenol and formaldehyde.

Thus its monomers are as follow:

phenol

C

6

​

H

5

​

OH

​

 and  

formaldehyde

HCHO

​

ii)Nylon−6,6

It is the condensation polymer of adipic acid and hexamethylene diamine.

Here 6 represents the number of carbon atoms in each monomer.

The two monomers of Nylon-6,6 can be given as follow:

adipic acid

HOOC−(CH
