Methyl anion The methanide anion ( CH − 3 ) exists only in rarefied gas phase or under exotic conditions. It can be produced by electrical discharge in ketene at low pressure (less than one torr ) and its enthalpy of reaction is determined to be about 252.2 ± 3.3 kJ / mol . [2] Meer weergeven 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. In formulas, the group is often abbreviated as Me. This Meer weergeven The reactivity of a methyl group depends on the adjacent substituents. Methyl groups can be quite unreactive. For example, in organic compounds, the methyl group resists attack by even the strongest acids. Oxidation Meer weergeven A methyl group may rotate around the R–C axis. This is a free rotation only in the simplest cases like gaseous methyl chloride CH3Cl. In most molecules, the remainder R … Meer weergeven • AdoMet Meer weergeven Methyl cation The methylium cation (CH+3) exists in the gas phase, but is otherwise not encountered.

Kindly login to access the content at no cost. WebIf the hydrogen atom departs and takes both electrons with it, we will produce a methyl cation. If, on the other hand, the hydrogen that dissociates leaves both electrons on the former methane, we will form a methyl anion. Finally, if the detaching hydrogen takes a single electron with it, we will form a methyl radical.
