Aniline point is a property of the

Solution (By Examveda Team)

Option A: Diesel - Diesel is a petroleum distillate commonly used as fuel in compression-ignition engines. The aniline point of diesel is typically higher compared to naphtha or gasoline. Diesel contains fewer aromatic hydrocarbons compared to naphtha, which results in a higher aniline point.

Option B: LPG - LPG (liquefied petroleum gas) consists primarily of propane and butane. It is not typically tested for aniline point as it is composed mainly of aliphatic hydrocarbons, which have lower aromatic content compared to naphtha.

Option C: Naphtha - Naphtha is a petroleum fraction containing a mixture of hydrocarbons, including both aliphatic and aromatic compounds. The aniline point of naphtha is determined by the temperature at which it becomes completely miscible with an equal volume of aniline. Naphtha contains a significant amount of aromatic hydrocarbons, which contribute to its aniline point.

Option D: Gasoline - Gasoline, like naphtha, is a petroleum fraction containing a mixture of hydrocarbons. It typically contains a higher proportion of light hydrocarbons and fewer aromatics compared to naphtha. Gasoline tends to have a lower aniline point compared to naphtha due to its lower aromatic content.

Conclusion:
Among the options provided, Option C: Naphtha is the petroleum product commonly associated with the aniline point. Naphtha contains a significant amount of aromatic hydrocarbons, which influence its aniline point. Therefore, the correct answer is Option C: Naphtha.
