Esters are chemical compounds derived from an acid where at least one -OH (hydroxyl) group is replaced by an -O- (alkoxy) group, while ethers are a class of organic compounds that contain an oxygen atom connected to two alkyl or aryl groups.
Carbonyl is a functional group characterized by a carbon atom double-bonded to an oxygen atom (C=O). Ketones are organic compounds containing a carbonyl group bonded to two alkyl or aryl groups.
The molecular units possess D2d symmetry and are built by strong π-interactions between two digallaanthracene monomers. Two symmetrical aryl group bridges between two gallium atoms are observed for the first time in the subunits of 2. By addition of a Lewis-base (THF, Pyridine) to 2, a ...
An ether is an organic molecule which has an oxygen atom bound to two carbon atoms in two sides. Therefore, ether is a type of organic molecule in which twoalkyl groups,aryl groups, or an alkyl and an aryl group, are connected to both sides of an oxygen atom. Depending on the R grou...
Examples of the carbonate ester include diaryl carbonates such as diphenyl carbonate and alkyl carbonates such as dimethyl carbonate and diethyl carbonate. The branching agent for imparting the polycarbonate with a branched structure is selected from compounds having at least three functional groups such...
The key difference between nucleophilic and electrophilic addition is that, in nucleophilic addition reactions, an electron-rich component combines with a
The carbanions formed from deprotonation of alkanes (at an sp3 carbon), alkenes (at an sp2 carbon), arenes (at an sp2 carbon), and alkynes (at an sp carbon) are known as alkyl, alkenyl (vinyl), aryl, and alkynyl (acetylide) anions, respectively. Carbocation An ion that has a ...
