Match the polymers in List-I with their characteristic in List-II and choose the correct option from the codes given below:
List - I | List - II |
|---|---|
(P) Bakelite | (1) Natural polymer |
(Q) Natural rubber | (2) Addition polymer |
(R) Buna-N | (3) Linear polymer |
(S) Cellulose | (4) Co-polymer |
| (5) Thermosetting plastic |
Options:
Answer:
A
Solution:
P → Bakelite
Thermosetting plastic
Cross-linked, not linear
Can be considered co-polymer (phenol + formaldehyde)
→ P → 4,5
Q → Natural rubber
Natural polymer
Addition polymer of isoprene
Linear polymer (cis-1,4)
→ Q → 1,2,3
R → Buna-N
Copolymer of butadiene + acrylonitrile
Addition polymer
Linear chain
→ R → 2,3,4
S → Cellulose
Natural polymer
Linear polymer of β-D-glucose units
→ S → 1,3
