A) Buna-N
B) PHBV
C) Neoprene
D) Nylon 6, 6
Correct Answer: B
Solution :
| Polymer | Monomers |
| Buna-N | \[C{{H}_{2}}=CH-CH=C{{H}_{2}}\] and \[C{{H}_{2}}=CH-CN\] |
| Neoprene | \[C{{H}_{2}}=CH-\underset{Cl}{\mathop{\underset{|}{\mathop{C}}\,}}\,=C{{H}_{2}}\] |
| Nylon- 6, 6 | \[HO-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-{{(C{{H}_{2}})}_{4}}-\overset{O}{\mathop{\overset{||}{\mathop{C}}\,}}\,-OH\] and \[N{{H}_{2}}-{{(C{{H}_{2}})}_{6}}-N{{H}_{2}}\] |
| PHBV | \[C{{H}_{3}}-\underset{OH}{\mathop{\underset{|}{\mathop{C}}\,}}\,H-COOH\] and \[C{{H}_{3}}-C{{H}_{2}}-\underset{OH}{\mathop{\underset{|}{\mathop{C}}\,}}\,H-C{{H}_{2}}-COOH\] |
