TLC. The mobile phase is a liquid, the stationary phase is a solid. Useful for seperating and comparing mobility of solids and some liquids dissolved in the mobile phase by their affinities to the solid phase relative to the mobile phase.

GLC. The mobile phase ia s gas, the stationary phase is a liquid on a solid support. same concept as TLC. useful for seperating gases by their affinities to the stationary phase...the mobility can then be compared to known compounds for possible identification.

What are the key differences between paper chromatography and thin layer chromatography?

Paper chromatography and thin layer chromatography are both techniques used to separate and analyze mixtures of substances. The key differences between them lie in the materials used and the method of separation. In paper chromatography, a strip of paper is used as the stationary phase, while in thin layer chromatography, a thin layer of silica gel or other material is used. Additionally, in paper chromatography, the solvent moves up the paper through capillary action, while in thin layer chromatography, the solvent is applied directly to the stationary phase. Overall, thin layer chromatography is faster and more efficient than paper chromatography, but both techniques have their own advantages and applications in analytical chemistry.


Other methods of purification and separation of organic compounds?

Various methods used for purification and separation of organic compounds are: i) Crystallisation ii) Fractional Crystallisation iii) Sublimation iv) Distillation v) Extraction with solvents vi) Chromatography.


What are the avantages of thin layer chromatography over paper chromatography?

Thin layer chromatography typically provides better resolution and separation of compounds due to the use of a uniform, inert stationary phase. It also offers faster separation times and requires smaller sample volumes compared to paper chromatography. Additionally, thin layer chromatography allows for visualization of separated compounds under UV light without the need for chemical staining.


How far do polar molecules travel in thin-layer chromatography (TLC)?

Polar molecules travel a shorter distance in thin-layer chromatography (TLC) compared to non-polar molecules.


What is the most suitable solvent for thin layer chromatography to separate compounds effectively?

The most suitable solvent for thin layer chromatography to effectively separate compounds is a mixture of polar and nonpolar solvents, such as a combination of ethyl acetate and hexane.

What are the differences between column and thin layer chromatography?

In chromatographic terms, TLC has great advantages over the other chromatography modes, such as Liquid Chromatography (LC), Column Chromatography (CC), Gas Chromatography (GC) and High Pressure Liquid Chromatography (HPLC).TLC's advantages are: (1) the ability to perform multiple analyses simultaneously; (2) speed and ease for scouting separation conditions, such as optimum solvent mixtures.

How can seprate p-nitro acetanilide mixture of para and ortho acetanilide?

The amide group on acetanilide is an ortho/para director, so a simple nitration should work: a mixture of sulfiric acid and nitric acid should be sufficient. Afterward, separation of the ortho and para compounds (by column chromatography, probably) would be necessary.


Are paper and thin layer chromatography types of planer chromatography?

What is the name of the method used to separate dyes?

Chromatography is the method used to separate dyes by allowing the components to move at different rates through a medium, such as paper or a column, based on their affinity for the medium and solvent. This technique separates the different dyes based on their molecular interactions with the moving phase.

What are some ways chromatography can separate chemicals in a mixture?

Chromatography separates chemicals based on their affinity for a stationary phase and a mobile phase, allowing them to travel at different rates. Different types of chromatography like gas chromatography, liquid chromatography, and thin-layer chromatography utilize different mechanisms such as adsorption, partition, ion exchange, and size exclusion to separate the components in a mixture. By adjusting the conditions like solvent polarity, temperature, and column material, chromatography can effectively separate complex mixtures into individual components.
