Question

a mixture of these four liquids are separated using a fractional distillation:toluene, b.p. 111 ocacetone, b.p. 56 ocbenzene, b.p. 80 ocmethanol, b.p. 65 ocwhich liquid will distill off first?

Answer 1

In fractional distillation, the liquid with the lowest boiling point is distilled first, which in this case is acetone with a boiling point of 56 °C.

Step-by-step explanation:

In fractional distillation, the component with the lowest boiling point will distill off first. Given the boiling points of the four liquids provided, acetone, with a boiling point of 56 °C, will be the first to distill off. This is because fractional distillation separates components of a mixture based on differences in boiling points, and the one with the lowest boiling point vaporizes first. The vapor then condenses and is collected as the distillate.
