Homework Answers
Ans: Polar solvents have greater eluting abiligty. Most of the carbonyl compounds, carboxylic acids, amines and amides having polar carbonyl, polar OH groups. These groups can form hydrogen bonding with polar solvents. Therefore these compounds are more soluble in polar solvents. Because of solubility polar solvents have greater eluting ability.

Ok, so what would happen if you are working with TLC and have a polar stationary phase (silica) and a mobile phase ( polar eluting solution) and you spot a nonpolar compound? Would the Rf values be greater than in a nonpolar mobile phase? I know in general if you are using TLC with polar silica and spot a nonpolar compound the nonpolar compound travels further (higher Rf values) because its chemical structure is different than the stationary phase compared...
