Chapter 11 Anti-inflammatory drugs: treatment of arthritis and gout. 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. 57 lessons. All right, our next functional group. The OH functional group is called a phenol (pronounced fee-nol) group if it is joined to a benzene ring. Each practice is centered on 1 organic compound. By Mike Bradley 12.21.2015. Psychological Research & Experimental Design, All Teacher Certification Test Prep Courses, What is Aspirin? groups, and how functional groups can be altered to provide a therapeutic benefit. Functional groups have different priorities when it comes to naming. lot of students mess this up. ending of our name here that we have a ketone present in this compound. That's more than 2,000 years ago. The fascinating emission can be attained through careful design or by selecting an appropriate organic chromophore that may shield the coordination shell from deactivating moieties and serve as an efficient antenna molecule. represent an ether, however, we have this carbonyl here. The chemical name of aspirin is acetylsalicylic acid. The half-life of aspirin in the blood stream is 13-19 minutes and the half-life of its metabolite salicylate is around 3.5-4.5 hours. So this is an amide, or an "amid" If we move the nitrogen further away from the carbonyl, let's go ahead and do that over here. so I drew the double bonds a little bit differently The benzene is not circled but you can see it there. So I'll first put in our ring, Consider the first step in the acid catalyzed hydrolysis of aspirin shown below; The structures of the products of the acid catalyzed hydrolysis of Aspirin are given in the reaction below. The molecular structure of an acetylsalicylic acid (aspirin) molecule is shown on the first page of Expt. There are a number of functional groups that contain a carbon-oxygen double bond, which is commonly referred to as a carbonyl. bonded to a carbonyl, and then for this oxygen, we have the rest of the molecule so Organic Chain Length. We have already seen some examples of very common functional groups: ethene, for example, contains a carbon-carbon double bond. The last compound in the video is 1-aminopropan-2-one.
