Draw the structures of the monomers of the following polymers :
(i) Teflon
(ii) Polythene
OR
What is the repeating unit in the condensation polymer obtained by combining `HO_(2)C CH_(2)CH_(2)CO_(2)H` (succinic acid) and `H_(2)NCH_(2)CH_(2)NH_(2)` (ethylene diamine) ?

Answer

`The monomer present in Teflon is Tetrafluoroethylene The structure of the monomer of polthene is `nCF_(2)=CF_(2)`
(ii) The monomer present in polythene is ethene The structure of the monomer of polythene is `nCH_(2)=CH_(2)`
`OR`
The repeating of the consensation polymer obtained by combining succinic acid ethylene diamine is
`(underset(N)overset(H)(|)-(CH_(2))_(2)-underset(N)overset(H)(|)-underset(C)overset(O)(||)-(CH_(2))_(2)-underset(C)overset(O)(||))_(n)` .

Explanation

Glucose is a hydrate of carbon `C_(6)(H_(5)O)_(6)` and dehydration on heating with conc. `H_(2)SO_(4)`.
