WebLiquids tend to be miscible with liquids of a similar polarity, and the same is true for nonpolar substances. In effect, the attractive or repulsive forces between molecules in the … WebEthyl acetate is a polar solvent, but it is often used in TLC. TLC’s stationary phase is usually silica gel, which is polar. Are solvents polar or nonpolar? Solvents are often categorized as polar or nonpolar, a factor of the solvent’s structure and charge that determines the types of substances that it can dissolve.

WebEthyl acetate is a polar solvent, but it is often used in TLC. TLC's stationary phase is usually silica gel, which is polar. I thought the whole point of TLC is to separate the polar compounds (travels less, low Rf) and nonpolar compounds (travels farther, high Rf). If the mobile phase is polar, what does TLC establish? WebEther, ethyl acetate, hexane and dichloromethane. You can simply dilute your reaction with more solvent and then wash with water.
