Organic Chemistry
The most suitable method of separation of $$1 : 1$$ mixture of ortho and para-nitrophenols is:
A reaction is carried out using aniline as a reactant as well as a solvent. How will you remove unreacted aniline?
Unreacted aniline can be separated by steam of distillation.
The most suitable method of separation of $$1 : 1$$ mixture of ortho and para-nitrophenols is:
What is the difference between distillation, distillation under reduced pressure and steam distillation ?
Explain, why an organic liquid vaporises at a temperature below its boiling point in its steam distillation ?
Those substance which can be separated by steam distillation are:
The boiling points of ethyl acetate and $${CH}_{3}OH$$, respectively are $${77}^{O}C$$ and $${65}^{o}C$$. Which of the following reactions can be shifted to the right by the distillation of the reaction mixture at about $${66}^{o}C$$. $$I. MeCOOEt+MeOH\rightarrow$$ $$II. MeCOOMe+EtOH\rightarrow$$ $$III. MeCOOMe+PhOH\rightarrow$$ $$IV. MeCOOPh+MeOH\rightarrow$$
In the destructive distillation of coal, at 443-503 K temperature, a middle oil or carbolic oil fraction is obtained. This fraction contains :
Aniline is separated from a mixture by:
What is the difference between distillation,distillation under reduced pressure and steam distillation?
Explain, why an organic liquid vaporises at a temperature below its boiling point in its steam distillation ?
How will you separate a mixture of o-nitrophenol and p-nitrophenol?
