Techni, Posted 6 years ago. Aspirin is a pain reliever and fever reducer, but if it's allowed to react with water then it can undergo hydrolysis, forming salicylic acid and acetic acid, which is no longer effective. Its molecular weight is 180.157 grams/mole. What are the function groups of aspirin? | Socratic Solved 1. Analyze the chemical structures of the pain | Chegg.com FT-IR spectrum of aspirin crystal | Download Scientific Diagram How to identify functional groups present in organic compounds. What is N-(2,2,2-Trichloroethyl)carbonyl] Bisnor-(cis)-tilidine's functional group? The male sex hormone testosterone contains ketone, alkene, and secondary alcohol groups, while acetylsalicylic acid (aspirin) contains aromatic, carboxylic acid, and ester groups. Thus, functional groups are a key organizing feature of organic chemistry. what wil be the systematic name for glucose that is C6H12O6, (2R,3S,4R,5R)-2,3,4,5,6-Pentahydroxyhexanal, What does the benz- in benzaldehyde stand for? Aspirin (2-ethanoyloxybenzoic acid or acetylsalicylic acid) hydrolyses to produce 2-hydroxybenzoic acid and ethanoic acid. Be sure to designate the location of all non-zero formal charges. During this era, the ancient Greek doctor Hippocrates gave women willow leaf tea to help relieve the pain associated with childbirth. Acetylation Reaction | What is Acetylation? Functional groups are atoms or small groups of atoms (two to four) that exhibit a characteristic reactivity. % And that's what makes this an amide. So, you can thank these groups for making aspirin one weak acid that is soluble in basic solutions, a great property to have, as it contributes to aspirin's ability to dissolve easily in your intestines. So an R group on one side of the oxygen, an R group on the other 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. The structure of Aspirin is given below. Functional groups | Alkanes, cycloalkanes, and functional groups Draw the structures of the products of the acid catalyzed hydrolysis of each of the following esters. So sometimes the students Aspirin is an approximately 150- to 200-fold more potent inhibitor of the (constitutive) isoform of the platelet enzyme (COX-1) than the (inducible) isoform (COX-2) which is expressed by cytokines, inflammatory stimuli, and some growth factors. Preventing hydrolysis Therefore, a higher dose of aspirin is required for its analgesic and anti-inflammatory effects in comparison to its antiplatelet action1.
