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 ...

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]
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.
Inductive effect. In Organic chemistry, the inductive effect in a molecule is a local change in the electron density due to electron-withdrawing or electron-donating groups elsewhere in the molecule, resulting in a permanent dipole in a bond. [1] It is present in a σ (sigma) bond, unlike the electromeric effect which is present in a π (pi) bond .
Methanol and its vapours are flammable. Moderately toxic for small animals – Highly toxic to large animals and humans (in high concentrations) – May be fatal/lethal or cause blindness and damage to the liver, kidneys, and heart if swallowed – Toxicity effects from repeated over exposure have an accumulative effect on the central nervous system, especially the optic nerve – Symptoms may ...
