Once there was a heavy downpour for about three hours in the early morning. Irfan and his family were finding it difficult to carry out their morning chores as the sewer water was flowing back into the toilets, the road outside was flooded with water and they could not move out. On this serious problem, Irfan called a meeting of the residents and said that we are using too much polythene bags and other plastic items which we throw here and there, which finally move into the drains and sewer lines which get choked. As these are non-biodegradable, they remain as such for long time. So we should use bags made up of cloth and jute which are biodegradable. Answer the following questions : (i) Name a polymer which is biodegradable. Write the structure of its monomers and the repeating unit. (ii) Write two uses of this polymer. (iii) Write any two values shown by Irfan.
