Is ethyl acetate non polar
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? WebOct 12, 2015 · 3. Your comment is not entirely true. The solvent system used depends upon the behaviour of your (crude) product on silica gel.
