Question

A synthetic rubber which is resistant to the action of oils, gasoline, and other solvents is:
a.) Buna-S
b.) Polyisoprene
c.) Neoprene
d.) Polystyrene

Answer 1

Hint: Polymer of chloroprene is the type of synthetic rubber which is not damaged by the action of various petroleum products like oil, gasoline and other solvents like acids. It is used in outdoor activities like making sealing gaskets, making wires.

Complete answer:
Buna-S is not a natural rubber. It is formed by the polymerization between styrene and butadiene. It gets damaged by the action of various petroleum products like oil, gasoline and other solvents like acids
Polyisoprene is a synthetic rubber. It is made by the polymerization reaction of isoprene. It gets damaged by the action of various petroleum products like oil, gasoline and other solvents like acids
Neoprene is also another type of synthetic rubber. It is manufactured by the Polymerization of chloroprene. This type of synthetic rubber is not damaged by the action of various petroleum products like oil, gasoline and other solvents like acids. It is used in outdoor activities like making sealing gaskets, making wires. It is quite high in demand.

$$nC{H}_2=\underset{Cl}{\underset{|}{C}}-CH=C{H}_2\to {[-C{H}_2-\stackrel{Cl}{\stackrel{|}{C}}=CH-C{H}_2-]}_n$$

Polystyrene is also a rubber which is not natural. It is synthetic. It is a polymer of styrene. It gets damaged by the action of various petroleum products like oil, gasoline and other solvents like acids.
Therefore, from the above given options neoprene that option C is correct. Neoprene does not get damaged by the action of oils, gasoline and other solvents.

So, the correct answer is “Option C”.

Note: Neoprene has high resistance to oils, gasoline and solvents because neoprene has low oxidation state as well as it is resistant to ozone and sun. It is chemically inert therefore; it can withstand petroleum-based mixtures whereas BUNA-S, polystyrene and polyisoprene they are also synthetic rubbers but they are not inert they get damaged by the action of oil, gasoline and other solvents.
