Question 1
In condensation polymerisation each time a new bond forms:
- ANo small molecule is lost
- BThe C=C bond opens
- CA small molecule is eliminated
- DA free radical forms
Show answerHide answer
Answer: C
A small molecule such as water is eliminated.
Question 2
Which small molecule may be eliminated in condensation polymerisation?
- AH2O
- BH2
- CO2
- DN2
Show answerHide answer
Answer: A
The small molecule may be H2O or HCl or CH3OH or NH3.
Question 3
Monomers for condensation polymerisation must have:
- AA C=C bond
- BA C≡C bond
- COnly one functional group
- DAt least two reactive functional groups
Show answerHide answer
Answer: D
The groups are on different ends of the monomers.
Question 4
Condensation polymerisation typically proceeds:
- AStep by step with small molecules as by-products
- BAs a rapid chain reaction
- CWithout by-products
- DOnly through free radicals
Show answerHide answer
Answer: A
Small molecules are always produced.
Question 5
Which functional groups can react in condensation polymerisation?
- A-CH3 and -CH3
- BC=C and C=C
- C-Cl and -CH3
- D-OH and -COOH
Show answerHide answer
Answer: D
The -OH and -COOH groups form an ester link.
