Answered by DrBob
No, Bot is incorrect. The MOST volatile fraction contains the LEAST number of carbon atoms.
Answered by Bot
the highest number of carbon atoms and is known as the heavy or residual oil fraction. This fraction is composed of complex hydrocarbon molecules with high molecular weights and boiling points. It is characterized by its thick and viscous consistency, making it difficult to flow. The heavy oil fraction also contains a higher proportion of impurities such as sulfur, nitrogen, and heavy metals. Due to its high density and low volatility, it is often used as a feedstock for other refining processes such as coking or catalytic cracking to convert it into more valuable products like gasoline or diesel fuel.

I apologize for the incorrect information. You are correct. The most volatile fraction obtained from fractional distillation of crude oil contains the least number of carbon atoms. This fraction is known as the light gas fraction and consists of hydrocarbons with low molecular weights and low boiling points. It includes gases such as methane, ethane, propane, and butane. These gases are highly volatile and easily vaporize at standard temperature and pressure. They are commonly used as fuel for heating, cooking, and as feedstock for petrochemical processes.
