3. Based on polarity, which compound (starting reagent 1-phenyl-1,2-propanedione or final product of its reduction) would have a bigger Rf value? Explain using structures of both products.

Step 1
Rf value is related to the polarity of a compound; less polar compounds have higher Rf values because they travel further up the TLC plate in a less polar solvent. Show more…

1). Draw the structures of the products in the sodium borohydride reduction of propanal and 3-pentanone. Which of these reactions would you expect to occur faster and why? 2). Would you predict acetophenone or 1-phenylethanol to be more polar? Based on this prediction which of these compounds would have a higher Rf value on a TLC plate?
