We can use the Bronsted-Lowry Acid-Base Theory to describe whether dimethylamine is an organic compound that can be described as an acid or base. An example of this process includes the use of the Hofmann rearrangement, to yield methylamine from acetamide and bromine. The general rule is that salts with ions that are part of strong acids or bases will not hydrolyze, while salts with ions that are part of weak acids or bases will hydrolyze. 0 (145) Ph. For example, many of the group 13 trihalides are highly soluble in ethers (R–O–R′) because the oxygen atom in the ether contains two lone pairs of electrons, just as in H 2 O.
