large amount of ester groups. Another synthetic fibre C is made of a polymer D which

consist of a large number of glucose units joined one after another (cellulose). [3]

a) Which fibre (A,B or C)is prepared from natural raw material?

b) Name the polymer D.

c) Which fibre could be - i) Nylon ii) Terylene?

d) Which among these is first true synthetic fibre?
