WebEthylamine, 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. WebHowever, the boiling point of methylamine is -6.3°C, whereas ethane's boiling point is much lower at -88.6°C. The reason for the higher boiling points of the primary amines is that they can form hydrogen bonds with each other as well as van der Waals dispersion forces … Alkanes provide reference compounds in which hydrogen bonding is not possible, … Amine oxides are relatively weak bases, pK a ca. 4.5, compared with the parent … Wij willen hier een beschrijving geven, maar de site die u nu bekijkt staat dit niet toe.
