Which of the following is a synthetic polymer?
Answer: B
The synthetic polymer is Nylon-6, 6.
Nylon-6,6 is a polyamide made in the laboratory and in factories by condensation polymerisation of hexamethylenediamine and adipic acid, each of which has six carbon atoms, hence the name. It is used for fibres, ropes, tyre cords and moulded parts.
Starch and cellulose are natural polymers of glucose made by plants, and proteins are natural polymers of amino acids made by living cells, so all three are natural rather than synthetic polymers.
