difference between simple distillation and fractional distillation.
plssssssss help .......i will mark you brainliest

Answer:
Simple distillation - Simple distillation is employed when the component of the liquid mixture have boiling point gaps close to fifty degrees. This involves boiling the mixture at first, and the compound with the lowest boiling point will start vaporizing. Let’s consider a mixture of two liquids. The vapour formed will be rich in the compound which has the lowest boiling point. At this point, the temperature remains steady until the fraction of the compound with the lowest boiling point in the liquid mixture reaches zero. Thereafter, the temperature again starts to rise until it reaches the boiling point of the compound with the highest boiling point.
:fractional distillation - Fractional distillation is a technique employed for many complex liquid mixtures, i.e., mixtures with components that have closer boiling points. For such systems, simple distillation will be meaningless. Therefore, a modified distillation is required. For fractional distillation to be effective, the components should be miscible.
