Let's look at some of the common mistakes that students make. We have already seen some examples of very common functional groups: ethene, for example, contains a carbon-carbon double bond. What are the function groups of aspirin? This is termed general acid catalysis. Acetylsalicylic acid (ASA) is a commonly used drug for the treatment of pain and fever due to various causes. The neutralization reaction can be used to determine the amount of aspirin (acetylsalicylic acid) present in commercially available aspirin tablets using a back (indirect) titration method. What functional groups are found in aspirin? So for example a carboxylic acid will have a higher priority than an alkene or alkyne. smart students mess up the difference between In secondary alcohols and tertiary alcohols, the central carbon is bonded to two and three carbons, respectively. Prostaglandins upregulate the sensitivity of pain receptors. So now we are talking about an alcohol, so this is an alcohol. Did you notice something unique about the chemical name of aspirin? If the carbon of an alkane is bonded to a halogen, the group is now referred to as a haloalkane (fluoroalkane, chloroalkane, etc.). All three compounds are aromatic. (b) What functional group is present in aspirin that is not present in the other NSAIDs? The synthesis of aspirin is known in organic chemistry as an esterification reaction. Ready to test your skills? What should I start learning after learning the basics of alkanes, alkenes, and alkynes? functional group present in the aspirin molecule. So here is an alkene functional group. Hydrocarbon functional groups, like alkenes and alkynes, are only able to have LDF. Aspirin is prepared from salicylic acid (see below). All rights reserved. All atoms should have complete octets (phosphorus may exceed the octet rule). 1: Identify the functional groups in the following organic compounds. What makes it different from acetophenone except for the fact that it's an aldehyde while the latter is a ketone? 1. One of the main destabilizing factors that aspirin needs to deal with is hydrolysis. It is so due to the phenyl ring and carboxylic groups having sp2 hybridization. The molecular structure of an acetylsalicylic acid (aspirin) molecule is shown on the first page of Expt. Chloroform, CHCl3, is an example of a simple haloalkane. And you can tell by the The carbon atom labeled 2 is an electrophile. Ionic salts of aspirin, such as sodium acetylsalicylate, are more soluble in water since they form stronger ion-dipole interactions with water. What functional groups are present in aspirin? copyright 2003-2023 Study.com. Ronald has taught college level chemistry. Here's another alkene, right, here's another carbon-carbon double bond. A functional group is a specific group of atoms within a molecule that gives rise to the characteristic chemical reactions of the molecule.
