Compounds 1-3 were analyzed by normal phase TLC (shown) using ethyl acetate as the eluent. Assign spots on the TLC plate to compounds 1-3.
1: 2-acetoxybenzoic acid 2: 2-hydroxybenzoic acid 3: benzoic acid
I asked a question about TLC and I received some mixed answers, so I'd like to see if my understanding of TLC is fine.
We're using normal phase TLC so lower Rf compounds will be more polar. $0.47$ is the most polar compound, $0.70$ is the least polar compound.
Ethyl acetate is polar. Does the eluent polarity just determine where the compounds will run on the TLC?
