Polarity refers to that state of a molecule or atom in which it bears both positively and negatively charged ends. The partial distribution of charge... Learn more about this topic: Polar vs. Nonpolar Covalent
The TLC plate below was developed in an 80:20 hexane: acetone solvent system. (Image) a) Is a 50:50 hexane: acetone solvent system more or less polar than 80:20 hexane: acetone? b) What would happen Which of the following components has the greatest solubility in hexane? (a) CH...
Amino acids I21 (Ile 1) to Y38 (Tyr 18) show an exceptional sidedness between nonpolar (light brown) and polar/basic (green/blue) amino acids. All six polar amino acids (Ser, Thr, Tyr) contain a hydroxyl group in their side chain. Download: Download high-res image (305KB) Download...
Why is it inadvisable to use ink pen to draw the origin and solvent lines on the TLC plate?Chromatography:Chromatography is an analytical method used to separate a mixture into its components using the differences in the affinity of the components to the mobile pha...
of semi-preparative HPLC purification of the isolated compounds (Figure 2). Their nature (UV spectral properties) and the behavior of these compounds during separation on reversed phase—the polar character of the compounds—gave us the idea of flavonoid glycosides with a high glycosylation pattern....
If the polarity of your mobile phase were lowered, what effect would be evidenced on the resulting TLC plate? How do u tell if a solute is polar or non polar? On what basis is it decided? Explain what is happening on the atomic ...

How does increasing the polarity of the solvent system affect the results of a TLC? If the polarity of your mobile phase were lowered, what effect would be evidenced on the resulting TLC plate? What is the definition of amine salts? What are the characteristics of water? Is it polar? Defi...
Thin-Layer Chromatography (TLC): Thin-layer chromatography is a chromatic technique that is used to separate the organic mixtures or non-volatile substances. This is a very simple, quick and easy method to separate the organic mixture. There are...
Fluorenone is more polar than Fluorene, which will elute off of your very polar Alumina column first when using hexane as the eluting solvent? Why? Chromatography : Chromatography is a technique used to separate the components of a mixture. This metho...
