Question 1
If the main chain of a polymer consists only of carbon atoms it is a/an:
- AAddition polymer
- BCondensation polymer
- CPolyester
- DPolyamide
Show answerHide answer
Answer: A
A carbon-only backbone indicates an addition polymer formed from alkenes.
Question 2
A polymer whose main chain contains oxygen or nitrogen atoms along with carbon is a/an:
