Table of common functional groups. For example, hexanoyl chloride 1 can be brominated in the alpha-position by NBS using acid catalysis. The reaction of enolates, enol ethers, or enol acetates with NBS is the preferred method of -bromination as it is high-yielding with few side-products. The electron pair of this \(\ce{C-H}\) bond then becomes part of the aromatic \(\pi\)-electron system and a substitution product of benzene, \(\ce{C_6H_5X}\), is formed. Hydrocarbons are a class of molecule that is defined by functional groups called hydrocarbyls that contain only Get information about a protecting group: MOM ether. Like many other sulfur-containing compounds, volatile sulfides have foul odors. The reaction is a route to aldehydes (C-CH=O), formamides (N-CH=O), and formate esters (O-CH=O).A reagent that delivers the formyl group is called a formylating agent.

As an example, consider a sample of water in a 2.3487 T external magnetic field, irradiated by 100 MHz radiation. The Gattermann reaction, (also known as the Gattermann formylation and the Gattermann salicylaldehyde synthesis) is a chemical reaction in which aromatic compounds are formylated by a mixture of hydrogen cyanide (HCN) and hydrogen chloride (HCl) in the presence of a Lewis acid catalyst such as AlCl 3. A sulfide is similar to an ether except that it contains a sulfur atom in place of the oxygen. In the formulas, the symbols R and R' usually denote an attached hydrogen, or a hydrocarbon side chain of any length, but may sometimes refer to any group of atoms.. Hydrocarbons. Glucose is produced when a glucoside is hydrolysed by purely chemical means, or decomposed by fermentation or enzymes.. The older method uses cis- and trans- which works well for the example given above because there are two H atoms and two Cl atoms. The aromatic ring is regenerated from this cationic intermediate by loss of a proton from the \(sp^3\)-hybridized carbon. The general formula of a carboxylic acid is RCOOH or RCO 2 H, with R referring to the alkyl, alkenyl, aryl, or other group.Carboxylic acids occur widely.
