Question

Match column I with column II.

Column I	Column II
P. Non-stick coating	(i). Melamine
Q. Flame resistant	(ii). Polystyrene
R. First fully synthetic fibre	(iii). Teflon
S. Thermoplastic	(iv). Nylon

Choose the correctly matched option.

• A. (P) - (ii), (Q) - (i), (R) - (iii), (S) - (iv)
• B. (P) - (iii), (Q) - (i), (R) - (iv), (S) - (ii)
• C. (P) - (ii), (Q) - (iii), (R) - (iv), (S) - (i)
• D. (P) - (iii), (Q) - (iv), (R) - (ii), (S) - (i)

Answer 1

The correct option is B (P) - (iii), (Q) - (i), (R) - (iv), (S) - (ii)

P. Teflon is polytetrafluoroethylene. It is non reactive, hydrophobic and highly strong carbon-flourine bond.

Q. Melamine is mixed with resins and has fire retardant properties due to its release of nitrogen gas when burned or charred.

R. Nylon is a synthetic fabric made from petroleum products. It is very light, strong and durable.

S. Polystyrene is a synthetic aromatic polymer made from monomer styrene. As a thermoplastic it is in a solid state at room temperature but flows if heated above ${100}^{0}C$.

Hence, option B os correct.
