Unformatted text preview: compounds we were testing for. Questions 1. If a very polar solvent such as methanol was used because a good solvent would pull the various compounds to different degrees of the TLC plate. Methanol would not do this because of its high polarity; it would only pull the other very polar compounds up the TLC plate while not attracting the non-polar compounds. This best solvent would be one with an intermediate polarity. The best way to have a solvent with an intermediate polarity is to mix them. 2. If there is too much solvent in the development chamber, the solvent would dissolve the compounds before they are able to separate, yielding no results....
