B) \[-(C{{H}_{2}}-\underset{\underset{\text{Cl}}{\mathop{|}}\,}{\mathop{C}}\,H){{-}_{n}}\]
C) \[-(\overset{\overset{H}{\mathop{|}}\,}{\mathop{N}}\,-{{(C{{H}_{2}})}_{6}}-\overset{\overset{\text{H}}{\mathop{|}}\,}{\mathop{N}}\,-\overset{\overset{\text{O}}{\mathop{|\,\,|}}\,}{\mathop{C}}\,-{{(C{{H}_{2}})}_{4}}-\overset{\overset{\text{O}}{\mathop{|\,\,|}}\,}{\mathop{C}}\,){{-}_{n}}\]
D)
Correct Answer: C
Solution :
Novolac, a condensation polymer of phenol and formaldehyde is a thermosetting polymer. Neoprene rubber \[\,-\,\,[C{{H}_{2}}-\underset{\underset{\,\text{Cl}}{\mathop{|}}\,}{\mathop{C}}\,=CH-C{{H}_{2}}]{{-}_{n}}\] and \[PVC-[C{{H}_{2}}-\underset{\underset{\text{Cl}}{\mathop{|}}\,}{\mathop{CH}}\,]{{-}_{n}}\]are thermoplastic polymers while nylon-66 \[-[NH-{{(C{{H}_{2}})}_{6}}-NH-\overset{\overset{\text{O}}{\mathop{||}}\,}{\mathop{C}}\,-(C{{H}_{2}})-\overset{\overset{\text{O}}{\mathop{||}}\,}{\mathop{C}}\,-{{(C{{H}_{2}})}_{4}}-\overset{\overset{\text{O}}{\mathop{||}}\,}{\mathop{C}}\,]{{-}_{n}}\] is a polyamide which is commonly known as fibre.You need to login to perform this action.
