If the solvent phase in TLC was 80:20 mixture of hexane and ethyl acetate, the polar compounds will not move as much as non-polar compounds.

If the solvent phase in TLC was 80:20 mixture of hexane and ethyl acetate, the polar compounds will not move as much as non-polar compounds. Correct Answer True

When the solvent is 80:20 mixture of hexane and ethyl acetate, the solvent will be mostly nonpolar. This means that the non-polar compounds will move further up the plate. In contrast the polar compounds will not have moved as much as the non-polar compounds. Hence the statement is true.
