The largest R group is ethane. It is an ethylamine. It has two other identical substituents, methyl groups, so this is N,N-dimethylethylamine . It is the lone pair of electrons on the electronegative nitrogen that gives amines their physical properties and reactivity. Like ammonia, amines are polar compounds.
Tertiary amines have no H-bond donor , since they have three alkyl groups on the nitrogen.
Reacting amines with strong acids leads to the protonation of the amine. Reactions Carboxylic acids are the organic acid functional group. Amines are the organic bases . The K b for triethylamine is 6.00 x 10 -4 . For example, let's calculate the pH of a 0.1 M solution of triethylamine.
