What similarity is there between the reactions of ammonia and triethylamine with water?
BASICITY OF AMINES
The pair of electrons in the filled, nonbonded orbital of ammonia or an amine such as triethylamine may be donated to any electron-deficient chemical species. In an aqueous solution, an amine is a weak base and accepts a proton from water in a typical acid-base reaction, like this:
NH3 + H2O <——–> NH4+ + OH-
The presence of the OH- …
