Chemistry Question - Macromolecule
Q)Fat and Terylene are:
A) Natural polymers B) Polyamides C) Polyesters D) Synthetic polymers
Try it out!

fats and terylene are polyesters. cos they contain the ester linkage, which is the -COO- bond.
fats are natural polyesters, while terylene is a synthetic polyester. hence, from this information, it is clear that only C(polyester) is the suitable answer.
Well Done. Fats are made up of 3 molecules of fatty acids and 1 molecule of glycerol (an alcohol that has 3 OH hydroxy functional group). As such, it forms 3 ester linkages.
I dont have to esplain Terylene. It should be covered in school textbooks. Do let me know if you need any clarification.

ReplyDeletepolyester.. answer is C i think.
ReplyDeletebecause fat contains ester and terylene as well i guess. not really sure about it. hmm.
A, natural polymers (terylene is not)
hence, Acannot be the answer.
B, Polyamides are for protein and nylon,thus B cannot be the answer.
D, Synthetic Polymers, this is obviously a no-no because fat is not synthetic. :D
correct me if im wrong yea, thanks.
