WebThe Rf value of compound A is 0 when a TLC plate is developed in diethyl ether. Compound B has a Rf value of 0 in pentane and 0 in diethyl ether. Which solvent would be better for separating a mixture of A and B by TLC? Explain. Diethyl ether should be used as the solvent because it displays a bigger difference in distance between the two ... Web(2) Solvent Effect on Rf Values. Three known compounds, anthracene, benzil, and triphenylmethanol will be developed in two different solvents. Prepare two identical plates, spotted with each of those compounds, and develop one in ethyl acetate and the other in a mixture of 95% hexane and 5% t-butyl methyl ether.
