Question

why acid amides are weakly basic in nature​

Answer 1

Answer: Acid amides are weakly basic in nature​  beacuse Amines have a single electron pair on their nitrogen atom, which is readily accessible for protonation. This is the root of fundamental nature. Any additional group that makes nitrogen more electron-dense enhances basicity.

What are the properties of Amines?

• It is gaseous in nature for the lower aliphatic amines. They smell like fish.
• At normal temperature, primary amines with three or four carbon atoms are liquids, while those with more carbon atoms are solids.
• In general, aniline and other arylamines are colourless. However, because of air oxidation, they get coloured when we store them in the open.
• Lower aliphatic amines can join water molecules via hydrogen bonding. As a result, these amines are water soluble.
• The molar mass of amines grows as the size of the hydrophobic alkyl component increases. Its solubility in water typically decreases as a result of this.
• Higher amines are not water soluble. Amines are easily dissolved by organic solvents like alcohol, benzene, and ether.
• Alcohols produce stronger intermolecular hydrogen bonds because they are more polar than amines.
• Because of hydrogen bonds formed by the nitrogen of one molecule and the hydrogen of the other, primary and secondary amines frequently interact with one another.
• Due to the presence of two hydrogen atoms, primary amines have a stronger intermolecular interaction than secondary amines.
• Due to the lack of a free hydrogen atom for bonding, there is no intermolecular interaction in tertiary amines.
• Amines boil at higher temperatures in the following order: primary > secondary > tertiary.
