A-Level Chemistry Question Analysis Topic: Chemistry - Short Questions
Exam Questions:
1) Name two poisonous gases which can be prepared from chlorine gas.
2) What are the products of hydrolysis of sugar?
3) Define themoplastic and thermosetting polymers. Given one example of each.
Answers:
For A-Level Chemistry, you should know:
1) Phosgene and mustard gas / sulphur mustard are the two deadly gases that can be made from chlorine gas.
2) Glucose and fructose are the two byproducts of sucrose hydrolysis. The glycosidic link is broken during hydrolysis, turning sucrose into glucose and fructose.
3) Thermoplastics: These are plastics that deform quickly when heated and are simple to bend.
Examples include the production of combs, toys, vehicle grills, and many types of containers using PVC and polythene.
Thermosetting polymers: These are plastics that, after been moulded, cannot be softened by heating.
Bakelite and melamine are two examples.
Work hard for your A-Level Chemistry examination!
End of analysis. Great!
