ncerthelp.comAmines act as Lewis bases due to the presence of lone pair of electrons on the nitrogen atom. More the K b (dissociation constant of base), higher is the basicity of amines. Lesser the pK b‘ higher is the basicity of amines. Aliphatic amines (CH 3 NH 2) are stronger bases than NH 3

www.chem.latech.eduAmines with fewer than six carbon atoms are infinitely soluble in water. Solubility results from hydrogen bonding between the amines and water. Even tertiary amines are water-soluble because of its ability to form hydrogen bonds. Odor or smell Methylamines (mono-, di-, and tri-) and ethylamine (gases) have ammonia-like smell.

www.ncert.nic.inAmines can be considered as derivatives of ammonia, obtained by replacement of one, two or all the three hydrogen atoms by alkyl and/or aryl groups. For example: Like ammonia, nitrogen atom of amines is trivalent and carries an unshared pair of electrons. Nitrogen orbitals in amines are therefore, sp3 hybridised and the geometry of amines is ...

Groups that are attached to the nitrogen atom are located using “N” as the position number. More complex primary amines are named

www.pearsonhighered.comTertiary amines, the leaving groups of quaternary ammonium ions, not only are less basic than the leaving groups of alcohols and ethers but also have a positive charge that enhances their leaving ability. Therefore, quaternary ammonium ions undergo elimination reactions as long as a strong base is present and the reaction is heated.
