Identify the correct statements from the following Electromeric effect is a permanent effect. Hyper conjugation is a temporary effect. Fractional distillation is used to seprate two liquids from a mixture if the difference in their boiling points is less . Different compounds are adsorbed on an adsorbent to different extents. the correct answer is

Write a note on the boiling point of a liquid.

Define boiling point of a liquid.

Why do we use different separation techniques for mixtures like grain and husk as well as ammonium chloride and salt though both of them are heterogeneous mixtures.What is the basis for choosing a separation technique to separate mixtures?

Various constituents of liquid possess different boiling points, So they can be separated by fractional distillation. It can be done by using claude's apparatus. When condensed air passed through Claude's apparatus, both oxygen and Nitrogen ger condensed separately. He and Ne are collected with liquid nitrogen. Ar, Kr, Xe are collected with liquid oxygen. After removal of N_2 by heating with CaC_2 He & Ne are cooled to 20 K with liquid H_2 After removal of O_2 with Cu, Ar, Kr, Xe are cooled with liquid nitrogen and Ar separated out. Finally liquid kr and Xe can be separated by fractional distillation : In this process the chemical that is not involved
