Two major differences between TLC and column chromatography should be stated. Concept introduction: Thin Layer Chromatography is a sensitive chromatographic technique which is used to analyze small quantities of the samples by solid-liquid adsorption method. Rectangular glass plate is coated with an adsorbent; sample to be analyzed is run on the plate in the developing chamber with the mobile phase to give spots of the analyzed sample. Column chromatography is a large scale solid-liquid adsorption chromatographic technique that can separate multigram amounts of mixtures. This is a preparative version of thin layer chromatography that permits separation and isolation of products by collection of eluted fractions.

Students have asked these similar questions

personality of each of them in terms of nucleophile vs. electrophile (some can be considered acids/bases but we are not looking at that here). Note you may have to use your growing intuition to figure out the personality of one of the molecules below but I believe in you! Rationalize it out based on what we have called strong versus weak electrophiles in past mechanisms. Consider using the memes below to help guide your understanding! A OH O B CH3 C Molecule A: [Select] Molecule B: [Select] Molecule C: [Select] Molecule D: [Select] > H D OH

Can you show me this problem. Turn them into lewis dot structures for me please and then answer the question because I cant seem to comprehend it/ The diagrams on the picture look too small I guess.
