Larger Kb values or smaller pKb values indicate stronger bases. The pKb value of ammonia is 4.75, and aliphatic amines, with a +I effect of alkyl groups, are stronger bases (pKb range: 3 to 4.22). Aromatic amines, with electron-withdrawing aryl ...

Amines react with mineral acids to form ammonium salts, demonstrating their basic nature. The basic character of amines is better understood through their Kb (base dissociation constant) and pKb (negative logarithm of Kb) values.

Amines exhibit basic character by reacting with acids to form salts. Amine salts, soluble in water but insoluble in organic solvents like ether, can be regenerated to the parent amine when treated with a base such as NaOH.

Amines are reactive due to the difference in electronegativity between nitrogen and hydrogen, as well as the presence of an unshared pair of electrons on the nitrogen atom. The number of hydrogen atoms attached to nitrogen determines the course of ...

The order of boiling points for isomeric amines is Primary > Secondary > Tertiary. Boiling points of amines, alcohols, and alkanes with similar molar masses generally follow the trend Amines > Alcohols > Alkanes.

Tertiary amines lack intermolecular association as they do not have hydrogen atoms available for hydrogen bond formation. Consequently, the order of boiling points among isomeric amines is Primary > Secondary > Tertiary.

Intermolecular association in primary and secondary amines is due to hydrogen bonding between the nitrogen of one molecule and the hydrogen of another. Primary amines exhibit stronger association because they have two hydrogen atoms available for hydrogen bond formation.

Butan-1-ol is expected to be more soluble in water than butan-1-amine because alcohols form stronger intermolecular hydrogen bonds with water compared to amines.

Amines and alcohols with nitrogen and oxygen having electronegativities of 3.0 and 3.5, respectively, exhibit different solubility patterns in water, with alcohols generally being more soluble.

Lower aliphatic amines are soluble in water due to the ability to form hydrogen bonds with water molecules. However, solubility decreases with increasing molar mass of amines because of the larger hydrophobic alkyl part.
