The system that forms maximum boiling azeotrope is

A

carbon disulphide acetone

B

benzene toluene

C

acetone-chloroform

D

n-hexane-n-heptane

Text Solution

Verified by Experts

The correct Answer is:
C
Mole fraction of solute
`=("Moles of solute")/("Moles of solute + Moles of solvent")`
`= (1)/(1+(1000)/(18))=(1)/(1+55.56)=0.0177`

The mixture that forms maximum boiling azeotrope is :

Which will from maximum boiling azeotrope ?

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
