Question

Calculate the Rf value compounds X and Y based on below information (X travels 1.0 cm, Y travels 0.5 cm from origin; the solvent front is 3.0 cm). Comment on the polarity of X and Y (2 points)

Answer 1

Hi Dear Friend my apologies for not able to answer second question (bottom one) as it requires experiment details.

First question answer:

Compound X R_f = 1.0 / 3.0 = 0.333

Compound Y R_f = 0.5 / 3.0 = 0.167

smaller R_f value represent that compound is more polar one

Hence Compound Y is more polar than compound X.

Hope this helped you!
