Naphtha obtained by fractional distillation of ___________ is passed over platinum.

Write one application of fractional distillation.

Mention the differences between Fractional distillation and Steam Distillation.

68% aqueous nitric acid cannot be concentrated by further fractional distillation. Give reason.

The solution which boil at constant temperature like a pure liquid and possess same composition in liquid as well as vapour state are called azeotropes. The components of azetropes cannot be separated by fractional distillation. Only non-ideal solutions form azeotropes. Solutions with negative deviation form maximum boiling azeotrope and the solutions with positive deviation form minimum boiling azeotrope. The boiling point of an azeotrope is never equal to the boiling points of any of the components of the azeotrope. Answer the following question: The azeotropic solutions of two miscible liquids Solutions which distill without any change in composition or temperature are called

A mixture of all isomers possible from the mono-chlorination of the structure is subjected to fractional distillation, then how many fractions will be obtained?

The following statements is true only under some specific conditions. Write the condition for it "Two volatile and miscible liquids can be separated by fractional distillation into pure components."

Write chemical equations for the following reactions : Steam is passed over hot aluminium.

The first fraction obtained during the fractionation of petroleum is
