1.

Distinguish between the term homopolymer and copolymer and give one example of each type.

Answer»

Solution :Polymers FORMED by the linking of a large number of one type of MONOMERS are called homopolymer. Example`underset ("Ethene")(nCH_(2)) = CH_(2) tounderset("Polythene (Homopolmer)")((-CH_(2)-CH_(2)-)_(n)`
Ethene Polythene (Homopolymer) Polymers formed by the linking of a large number of two or more types of monomers are called COPOLYMERS.
Example
`nH_(2)N(CH_(2))_(6)NH_(2)+ nHOOC(CH_(2))_(4)COOH to [-NHunderset("Nylon 6,6 (corpolymer)")(NHCO(CH_(2))_(4)CO-)]_(n) + nH_(2)O`
