The Malonic Acid synthesis is similar to the Acetoacetic Ester synthesis It uses diethyl malonate as the main starting material Draw the structure of diethyl malonate (malonic ester) Diethyl malonate can be hydrolyzed back to malonic acid and if heat is applied after the hydrolysis, will decarboxylate. Draw the mechanism for this transformation starting with malonic acid. Indicate the new C-C bonds in each molecule and then provide the organohalides which were used to synthesize each compound using the malonic...

Discussion Questions The structures of acetanilide and malonic acid are provided below 1. For each structure, draw circles around the polar and nonpolar regions of the molecule, and label each circled regiorn with the type of intermolecular attractive force it can use to interact with other molecules. Acetanilide Malonic Acid но CH2 OH 2. Now-thoroughly explain (on the basis of polarity/nonpolarity and intermolecular attractive forces) how the acetanilide was separated from the malonic acid by recrystallization from water. And explain...

EXPERIMENT 20 CSI: SMU Part 2. Synthesis of an Ester. Esters are compounds of the form RCOOR'. They occur naturally in many plants and animals, and can be synthesized. They have a pleasant aroma usually described as "fruity of flowery". In a Fisher esterification an ester is formed from the reaction of a carboxylic acid and an alcohol with a strong acid as a catalyst. The OH contained in the carboxylic acid group 1s replaced with the alkoxy group (O-R")...
