Ch15_PT MULTIPLE CHOICE. They are a major component of proteins and enzymes, nucleic acids, alkaloid drugs, etc. They have boiling points comparable to those of ethers (Table 15. Laboratory 25: Properties of Amines and Amides Chemical Properties - Amines Amines are considered weak bases due to the unshared pair of electrons which can attract a proton from a water molecule. 1 Amides: Nomenclature and Physical Properties 25. In the IUPAC system, the amines are regarded as alkanamines, e. 3 Polyamides: Condensation Polymers 25. is attached to the root alkyl name. - As a result of hydrogen bonding, primary and secondary amines have _____. Amines possess a characteristic ammonia smell, liquid amines have a distinctive "fishy" smell. The R-groups can be classified in many different ways, several of which are described below.
