Discuss the differences observed in the IR and NMR spectra of 3-nitrophthalic acid and luminal that are consistent with reduction of the nitro function to an amino group
Explain why the Rf values changed when the eluant was changed from 100% petroleum ether to a 95:5 mixture of petroleum ether-ethyl acetate.
A solution of phosphoric acid was made by dissolving 10.0g H2PO4 in 10.0 mL of water. The resulting volume was 104 mL. Calculate density, mole fraction, molarity, and molality of the solution.
Analysis of the products revealed two methylated sugars: 2,3,6-tri-O-methyl-D-glucose, 2,4-di-O-methyl-D-glucose and 2,3,4,6-tetra-O-methyl-D-glucose. The ratio of these sugars was 20:1:1. determine the structure of the polysaccharide?
