Experimental Outline In its simplest form, the aldol condensation is a self-addition involving two molecules of the same aldehyde or ketone, in the presence of a base, and results in the formation of a new carbon-carbon bond joining the carbonyl carbon of one molecule to the a-position of the second. In many cases - if the reaction conditions aren't sufficiently mild - the initially formed aldol product reacts further in an elimination reaction to give what is...

3. Let’s now consider a slightly different reaction, a reaction in solution: Glucose (aq)--->Fructose (aq) a). Give the expression of the equilibrium constant K in terms of the concentration of glucose and fructose in the solution. What kind of reference states do you assume for the two solutes here? b). If someone determined that this conversion has ∆rG0=+1.7kJmol-1 in aqueous solution. If you start off with a solution of 0.1M of pure glucose in the solution, what would be final...
