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 ...
Channel 3 or Channel 3 HD (Thai: ช่อง 3 เอชดี, formerly known as สถานีโทรทัศน์ไทยทีวีสีช่อง 3, lit. 'Thai Television Color Channel 3') [3] is a Thailand and Bangkok's first commercial free-to-air television network that was launched on 26 March 1970 as Thailand and Bangkok's first commercial television station.
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.

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.
History. These reagents were discovered by Henry Gilman and coworkers. [3] Lithium dimethylcopper (CH 3) 2 CuLi can be prepared by adding copper (I) iodide to methyllithium in tetrahydrofuran at −78 °C. In the reaction depicted below, [4] the Gilman reagent is a methylating reagent reacting with an alkyne in a conjugate addition, and the ...
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.
Ethylamine, also known as ethanamine, is an organic compound with the formula CH 3 CH 2 NH 2. This colourless gas has a strong ammonia -like odor. It condenses just below room temperature to a liquid miscible with virtually all solvents. It is a nucleophilic base, as is typical for amines.
