Question
Table 3 Name of eluent Name of Distance traveled Distance traveled Compound Revalue by solvent by b) Which compound, amine or alcohol, is more polar? Explain using your results from the chromatogram(s) you generated and your results in Table 3. A useful transformation in organic synthesis is the conversion of an amine (benzylamine) into an aldehyde (benzaldehyde). Prepare one TLC and investigate how their polarities compare. (a) Record your results in table 4. 4. Table 4 Name of eluent Name of Distance traveled Distance traveled Rr value Compound nzylmin by compound 1.8 by solvent 9719 (b) Which compound, amine or aldehyde, is more polar? Explain using your results from the chromatogram you generatedExplanation / Answer
Table 3, amine and alcohol
(b) Alcohol is more polar than the amine. The Rf value for alcohol is lower than that of amine, which tells us that the alcohol stayed at the column for longer period of time, has more strong interaction with the stationary phase than the amine.
4. amine and aldehyde
Table 4
(b) From the Rf values given in Table 4, aldehyde was found to be more polar than the amine. Therefore, according to this chromatogram, aldehyde interacts strongly with the stationary phase. The Rf value for aldehyde was lower than the amine.
