Question
The following molecule was spotted on the TLC (silica gel) plate and eluted with 1:1 ethyl acetate:methylene chloride. What would you expect the Rf to be after the elution?
The Rf value will be high due to low affinity sodium benzoate has for the polar stationary phase and low affinity for the mobile phase
The Rf value will be near 0 due to strong affinity sodium benzoate has for the polar stationary phase and strong affinity for the mobile phase
The Rf should be near 0 since sodium benzoate has a weak affinity for the relatively non-polar mobile phase and strong affinity for the polar stationary phase
Explanation / Answer
c. The Rf value will be near 0 due to strong affinity sodium benzoate has for the polar stationary phase and strong affinity for the mobile phase
