I know that quaternary ammonium salts can be used as fabric softeners. There are many more uses but for a level chemistry just the one use should be enough so long as it is fairly common.
quaternary amines or in slang - quats
they form insoluble quaternary ammonium salts
For example ammonium salts (nitrate, sulfates) are used as fertilizers in agriculture.
No, ligands are those which may donate pairs of electrons to a metal ion quaternary salts of nitrogen do not have free electrons pairs.
Ammonium salts are the products of the reactions between ammonium hydroxide and acids.
Ammonium salts are the products of a reaction between ammonium hydroxide an an acid.
All salts that contain a positive ion including a nitrogen atom bonded to four carbon atoms by single bonds. The lowest ionic mass example is tetramethyl ammonium, which has a single positive charge.
NH4+.
disadvantage
Metals and ammonium form generally salts.
it works as a catalyst
