Infobox references. In organic chemistry, methenium (also called methylium, carbenium, [2] methyl cation, or protonated methylene) is a cation with the formula CH+. 3. It can be viewed as a methylene radical (:CH. 2) with an added proton (H+. ), or as a methyl radical (• CH. 3) with one electron removed. It is a carbocation and an enium ion ...
In chemistry, methanium is a complex positive ion with formula [C H 5]+ (metastable transitional form, a carbon atom covalently bonded to five hydrogen atoms) or [CH3(H2)]+ (fluxional form, namely a molecule with one carbon atom covalently bonded to three hydrogen atoms and one dihydrogen molecule), bearing a +1 electric charge.

Trimethylamine (TMA) is an organic compound with the formula N(CH 3) 3. It is a trimethylated derivative of ammonia. TMA is widely used in industry. [5] [6] At higher concentrations it has an ammonia-like odor, and can cause necrosis of mucous membranes on contact. [7] At lower concentrations, it has a "fishy" odor, the odor associated with ...
Acetaldehyde (IUPAC systematic name ethanal) is an organic chemical compound with the formula CH 3 CHO, sometimes abbreviated as Me CHO. It is a colorless liquid or gas, boiling near room temperature. It is one of the most important aldehydes, occurring widely in nature and being produced on a large scale in industry.
Methylamine is an organic compound with a formula of CH 3 NH 2. This colorless gas is a derivative of ammonia, but with one hydrogen atom being replaced by a methyl group. It is the simplest primary amine. Methylamine is sold as a solution in methanol, ethanol, tetrahydrofuran, or water, or as the anhydrous gas in pressurized metal containers ...
Methyl group. In organic chemistry, a methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms, having chemical formula CH3 (whereas normal methane has the formula CH4). In formulas, the group is often abbreviated as Me. This hydrocarbon group occurs in many organic compounds.
