Hello and welcome to the forum! I would be happy to provide a response to your question about fractional distillation and normal distillation.

Fractional distillation and normal distillation are both methods used to separate a mixture of liquids based on their boiling points. However, there are some key differences between the two processes.

Normal distillation, also known as simple distillation, involves heating a mixture of liquids until the one with the lowest boiling point vaporizes first. The vapor is then condensed and collected, leaving behind the other liquid(s) in the original mixture. This process is effective for separating liquids with a large difference in boiling points.

On the other hand, fractional distillation involves the use of a fractionating column, which is a long tube packed with materials that increase the surface area for vaporization and condensation. As the vapor rises through the column, it cools and condenses on the packing material, and then re-vaporizes. This process is repeated multiple times, allowing for more efficient separation of liquids with closer boiling points.

In summary, the main difference between fractional distillation and normal distillation is the use of a fractionating column in fractional distillation, which allows for more precise separation of liquids with similar boiling points. Normal distillation is typically used for separating liquids with a larger difference in boiling points, while fractional distillation is more suitable for separating liquids with smaller differences in boiling points. I hope this helps answer your question.
