Similarly one may ask, what are the physical properties of amides?The amides generally have high boiling points and melting points. These characteristics and their solubility in water result from the polar nature of the amide group and hydrogen bonding (Figure 15.14.Similarly, are amides acidic basic or neutral? Basicity. Compared to amines, amides are very weak bases. While the conjugate acid of an amine has a pKa of about 9.5, the conjugate acid of an amide has a pKa around −0.5. Therefore, amides don’t have as clearly noticeable acid–base properties in water. In respect to this, what are the properties of amines? Primary amines with three or four carbon atoms are liquids at room temperature whereas higher ones are solids. Aniline and other arylamines are generally colourless. However, they get coloured when we store them in open due to atmospheric oxidation. Lower aliphatic amines can form hydrogen bonds with water molecules.How does an amide differ from an acid?Amides with N−H bonds are weakly acidic, the usual Ka being about 10−16: Nonetheless, amides clearly are far more acidic than ammonia (Ka∼10−33), and this difference reflects a substantial degree of stabilization of the amide anion.
