Question

compounds A and B are found in a mixture.Rf values for both compounds were calculated. which of the following sets of Rf valueels would reflect the largest separation between A and B? rfA=0.5 and rfb=0.6 or rfa=0.1 and rfb=0.1 or rfa=0.6 and rfb=0.5 or rfa=0.4 and rfb=0.2 ?

Answer 1

Rfa=0.4 and Rfb=0.2 valueels reflect the largest separation between A and B. The greater the difference between Rf, the better the substances can be separated.
