geometric isomers of dibenzalacetone

The pKa of phosphoric acid is ~ 2. Where do you expect the equilibrium to be in an acid-base reaction of phosphoric acid with cyclohexanol. The essential pKa of cyclohexanol is ~16. with phosphoric acid having a pKa ~2, the equilibrium will shift toward the less acidic compound, in this case cyclohexanol. OTHER SETS BY THIS CREATOR.

    Nov 12, 2019 The aim of this experiment is to estimate the relative ratio of geometric isomers of Dibenzalacetone that was prepared via the crossed-aldol condensation by reacting benzaldehyde with acetone. Dibenzalacetonewas synthesized in the lab from benzaldehyde and acetone under basic conditions. The GC-MS was used to relate the molar mass of the product.

    2.Write the formula to show the possible geometric isomers of dibenzalacetone. Which isomer would you find to be the most stable and why? The E-E isomer of dibenzalacetone is most stable because it has the highest melting point. This tells me that it is the most stable and less volatile than the other isomers which have a lower melting point. 3 ...
