    In the above table we have acids of three different kinds, all capable of yielding amides. (1) In acetic and benzoic acids we have examples of acids which are simply monobasic. The amides of these acids are called monamides, and are very simple: Aeetamide, Benzamide. C,H30 1 C,H,0 1 H J^ N. H [ N. H J H j They differ from the corresponding amines, just as the acids do from the alcohols. (2) Oxalic and mesoxalic acids are examples of dibasic acids. They are, in fact, dihydrates of the radicals CgOg and C3O3. Now these radicals, being diads, are capable of replacing two atoms of hydrogen in the double molecule of ammonia. In this way neutral amides of the kind called diamides are formed. Urea is by far the most important of the diamides. Oxamide Urea (oxalyl diamide) (carbonyl diamide). CAl CO] hJn, hJ HJ But from all dibasic acids a monad as well as a diad radical may be derived by merely deducting HO. Thus from sulphuric acid, SO2 HO HO, we get not only the diad radical SOj, but also the monad radical SO2 HO. The following formulae exhibit this : (SO2) HO HO (SO2 HO)' 01 (SO2) CI,.
