It is a non-selective NSAID as it irreversibly inhibits both cyclooxygenase (COX) enzymes involved in converting arachidonic acid to prostaglandins and thromboxane 3. lot of students mess this up. Aspirin is only slightly soluble in water, so if we add it to the reaction mixture the product would rather clump together than be in the water phase. functional group a particular group of atoms that form the same structural pattern from one organic molecule to another ketone an organic compound containing a carbonyl group bonded to carbon atoms on both sides The structure of acetyl salicylic acid, or aspirin, is shown to the right.

The reason: an ester has replaced the acidic phenol in ASA. In the synthesis reaction of aspirin, the salicylic acid is the limiting reactant and the acetic anhydride is in excess. Identifying Multiple Functional Groups - ChemSimplified Chloroform, CHCl3, is an example of a simple haloalkane. It has a carboxylic acid group, which can be ionized or not, depending on the conditions. Answer link Instead of trying to memorize both equations, we can build a general rule that bromine reacts with compounds that contain a C=C double bond to give the product expected from addition across the double bond. The reaction that is used for the synthesis is the one between an excess of acetic anhydride that is added to a measured mass of salicylic acid in the presence of a catalyst, sulfuric acid. Solved 1.
