Final answer:
In TLC, a substance that is strongly attracted to the stationary phase will travel more quickly than a substance that is not strongly attracted.
Step-by-step explanation:
False. In TLC (Thin Layer Chromatography), a substance that is strongly attracted to the stationary phase will travel more quickly than a substance that is not strongly attracted. This is because the mobile phase (solvent) will carry the substance along with it, and the more strongly attracted substance will have a stronger interaction with the stationary phase, causing it to move more slowly. On the other hand, a substance that is not strongly attracted will have a weaker interaction and will travel more quickly.
