Thin layer chromatography (TLC) is used all the time to monitor reactions. Below is a typical TLC plate when viewed under UV light, showing a reaction that is almost complete. Note that when we monitor a reaction, we always include a 'mixed spot' (mix) that has both the starting material (SM) and the reaction products (react) in it. Sometimes the starting material and product can have very similar R_f values, so a mixed spot can help us 'spot' this.

For the TLC plate below, fill in the R_f values (to two decimal places) for the starting material (SM) and the product (new spot seen in the 'react' spot).
