Question

Which fraction is used as a solvent for paints, resins, rubber etc?
A.$90\% $ benzol
B.$50\% $ benzol or $90\% $ Toluol
C.solvent naphtha or benzin
D.all of the above

Answer 1

Hint: The Solvent for paint, resins and rubber are used to dissolve the other components required in them evenly. It is required to form the desired consistency of the paint that the solvent needs to be desired of.

Complete step by step answer:
Now to know, which fraction is used as a solvent for paint, raising rubber, etc. We need to study the importance and the properties of the above given options.
 $90\% $ benzol: Benzol primarily contains benzene and toluene as mixture. It is a coal-tar product. Benzel's main purpose was to serve as a motor fuel when mixed in petrol.
$50\% $ Benzol and $90\% $ Toluol: Now from the above observation, we know that Benzole is used as motor fuel when mixed in petrol. The change in its percentage only changes the quality of the fuel and does not change its purpose. The commonly known name of toluol is toluene. Toluene has a molecular formula ${C_7}{H_8}$. When benzene is attached with a methyl group, it is known to be toluene or methyl benzene. It is an aromatic compound and it is also flammable and colourless. Now the major use of toluene is in aviation fuel, high octane fuel and also in dyestuffs and explosives. It is also used as solvents but only for gums and lacquers.
Solvent naphtha or benzin: Now, naptha is a great paint thinner. It is used as solvents for fuel, resins, rubber etc. It is powerful than many other spirits therefore we require a less amount of it.
Hence, Solvent naphtha and benzene are used as a solvent for paints, raisins and rubbers, etc.
And hence option C is the correct answer.

Note:
In organic chemistry, many elements are famously known by its common name rather than their IUPAC nomenclature like ethanoic acid is popularly known as acetic acid and ethandioic acid as oxalic acid.
