Question

What is the name of this functional group? Draw the structural formula of the compound CH_3CHO, showing all bonds between atoms. Thin Layer Chromatography (TLC) is also called Thin Layer Adsorption Chromatography. In this technique, organic compounds are adsorbed, to different extents, to the solid phase, resulting in their separation. Occasionally, the word "absorption" is mistakenly used to describe thin layer chromatography instead of "adsorption". Describe the difference between a substance that is adsorbed vs. one that is absorbed.

Explanation / Answer

adsorption : it is the phenomenon takes place only surface of solid and liquids . that means accumulation of molecules on the surface of solid and liquid . it is surface phenomenon

example :) 1) charcoal adsorb gases .

absorption: in this molecules distribute throught the bulk . absorption is interior phenomenon.

examples : when chalk stick in ink . when chalk stick dipped in ink , color only concentrated on surface and solvent penetrate into the interior parts .

with respect to ink adsorption takes place

with respect to solvent abosrption takes
