Solution distilled without change in composition at a temperature is called

A

Reactivity `HCHOgtCH_(3)CHOgtCH_(3)COCH_(3)`

B

Reactivity `PHCHOgtHCHO`

C

Electrophilicity of carbonyl carbon `HCHOgtCH_(3)CHOgtCH_(3)COCH_(3)`

D

Electrophicityy of carbonyl carbon: `HCHOgtPhCHO`

Text Solution

Verified by Experts

The correct Answer is:
B
Polarity of carbonyl group is reduced in `Ph-CHO` due to resoance. Hence the respective carbonyl carbon is less electrophilic that that propanal and therefore less reactive.
Hence reactivity order `(H_(3)"CC"H_(2)CH)gtPhCHO)`

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
