Rf values will depend upon the mobile phase you used and the temperature of the system as well as the nature of your paper you used to spot your samples. Spotting samples of the cereal spiked with your analyte of interest at different levels and spotting samples of the amino acid at different levels would be the technique used to estimate the ... If 2 compounds have Rf values of .38 and .55, how far will they be separated from each other on a plate when the solvent front is developed to 9cm? 1.52(=4.95-3.42)(x/9=.38) For compounds having similar Rf values, what could be done to improve the separation of the spots? To a solution of cinnamaldehyde (2 g, 15.13 mmol) in 14 mL of 95% ethanol in a sealed 50 mL round bottom flask was added with NaBH 4 (0.228 g, 6.05 mmol).

Nov 09, 2009 · why does Cinnamyl alchohol have a lower Rf value than cinnamaldehyde? Explain using your knowledge of the types of interactions that determine the mobility of a compound during column chromatograpy Answer Save Since the trans,trans isomer is essentially symmetrical, it has little or no molecular dipole. The cis,trans isomer has a small molecular dipole because it is asymmetric. Therefore the cis-trans isomer has more affinity for the stationary phase (giving it the Rf value of 0.83). Am I on the right track here? Cinnamaldehyde is the aldehyde that gives cinnamon its flavor and odor. Cinnamaldehyde occurs naturally in the bark of cinnamon trees and other species of the genus Cinnamomum like camphor and cassia. These trees are the natural source of cinnamon, and the essential oil of cinnamon bark is about 90% cinnamaldehyde.
