The Carbonyl Group - Angelo State University
www.angelo.eduThe Carbonyl Group 2 The Carbonyl Group • The carbonyl group (C=O) is found in aldehydes, ketones, and many other organic functional groups. • The carbon and oxygen in the carbonyl group are sp2-hybridized, with bond angles of 120°. •In ketones, two carbon groups are attached to the carbonyl carbon, while in aldehydes at least one
12.112.112.1 Nomenclature and Structure of Carbonyl Group
ncert.nic.inCarbonyl Group π Fig.12.1 Orbital diagram for the formation of carbonyl group The carbon-oxygen double bond is polarised due to higher electronegativity of oxygen relative to carbon. Hence, the carbonyl carbon is an electrophilic (Lewis acid), and carbonyl oxygen, a nucleophilic (Lewis base) centre. Carbonyl
Ketones and Aldehydes - Rutgers University
crab.rutgers.eduThe carbonyl group is of central importance in organic chemistry because of its ubiquity. Without studying the carbonyl group in depth we have already encountered numerous examples of this functional group (ketones, aldehydes, carboxylic acids, acid chlorides, etc). The simplest carbonyl compounds are aldehydes and ketones.

as.vanderbilt.eduChapter 23. Carbonyl Condensation Reactions As a result of the large dipole of the carbonyl group: 1. The carbonyl carbon is electrophilic and is the site of addition reactions by nucleophiles; 2. The α-protons are acidic and can be deprotonated by strong bases to give an enolate, which are nucleophiles and react with electrophiles. C CH O B ...

studyclix.blob.core.windows.netcarbonyl group for aldehydes is sometimes written as C=OH or CHO as it’s at the end of a chain there is a hydrogen as well. The ending for aldehydes is -anal (eg: propanal) and for ketones it’s -anone (eg: propanone). The result of the addition of the carbonyl group is the boiling points and solubility change. Boiling Point
