The molecule consists of a nitrogen atom with two methyl substituents and one hydrogen. Dimethylamine is a weak base and the pKa of the ammonium CH3-NH 2-CH3 is 10.73, a value above methylamine (10.64) and trimethylamine (9.79). Dimethylamine reacts with acids to form salts, such as … See more Dimethylamine is an organic compound with the formula (CH3)2NH. This secondary amine is a colorless, flammable gas with an ammonia-like odor. Dimethylamine is commonly encountered commercially as a … See more It is basic, in both the Lewis and Brønsted senses. It easily forms dimethylammonium salts upon treatment with acids. … See more Dimethylamine is not very toxic with the following LD50 values: 736 mg/kg (mouse, i.p.); 316 mg/kg (mouse, p.o.); 698 mg/kg (rat, p.o.); 3900 mg/kg (rat, dermal); 240 mg/kg (guinea pig or … See more Dimethylamine is found quite widely distributed in animals and plants, and is present in many foods at the level of a few mg/kg. See more Dimethylamine is a precursor to several industrially significant compounds. It reacts with carbon disulfide to give dimethyl dithiocarbamate, a precursor to zinc bis(dimethyldithiocarbamate) and other chemicals used in the sulfur vulcanization See more • Methylamine • Trimethylamine See more • International Chemical Safety Card 0260 (gas) • International Chemical Safety Card 1485 (aqueous solution) See more WebMay 19, 2024 · As methylamine has the least number of alkyl groups as compared to dimethylamine and trimethylamine, at this point, it would be the strongest base. However, …

WebMar 29, 2016 · METHYLAMINE. CH3NH2 contains a methyl group, which is electron-donating. That is, it inductively donates electrons through the N−Br bond towards nitrogen, which "activates" the nitrogen's Lewis base behavior since there is more electron density around it. The more electron density around the nitrogen, the more it has available to … WebThe combined effect of the pushing effect of the alkyl group (+I effect), steric hindrance and the salvation of amines causes the basicity order to be: (basicity of tertiary is almost the same as that of primary). NH 3 < primary amine ~ tertiary amine < secondary amine. So, here Dimethylamine is the strongest base. my health corio
