Passage

The polymer is a very large molecule that is made up of repeating small molecular units called monomers. The chemical reaction that unites the monomers is called polymerization. There are homopolymers, copolymers depending upon the type of monomers present in them.

Which of the following monomers will give radical polymerization most readily?
 

1. ${\mathrm{C}}_6{\mathrm{H}}_5\mathrm{CH}={\mathrm{CH}}_2$

2. ${\mathrm{CH}}_2={\mathrm{CH}}_2$

3. ${\mathrm{CH}}_3-\mathrm{C}\left({\mathrm{CH}}_3\right)={\mathrm{CH}}_2$

4. ${\mathrm{CH}}_3-\mathrm{CH}={\mathrm{CH}}_2$

Which of the following cannot be used as a plasticizer?

1. 

2. 

3. cresyl triphosphate

4. Di- n-octyl phthalate

Which of the following are biopolymers?

(a) Leather

(b) Nucleic acids

(c) Orlon

(d) Bakelite

1. a,b

2.a,b,c

3.b

4.a

Which of the following compounds not contain amide linkage/group?

(1) Acetamide

(2) Nylon-6

(3) Cellulose

(4) Proteins
