You do a Thin-layer chromatography and use 3 different
eluents:
TLC A: Ethyl acetate
TLC B: Ethyl acetate and formic acid
TLC C: Ethyl acetate and ammonia
Write the order of elution which you would expect for
each TLC and explain your reasoning for the following
substances:
(Clearly highlight which molecule will be
protonated/deprotonated)
A) Paracetamol, Coffein and Acetylsalicylic
acid
B) Paracetamol, Salicylic acid and Salicylic
Amine
