One way of naming amines is to name in alphabetical order the alkyl groups attached to the nitrogen atom, using the prefixes di- and tri- if the groups are the same. An example is isopropyl amine whose formula is shown above. What are names for (a), (b), (c), and (d)? Build handheld molecular models for the compounds in parts (a)–(d).
Write bond-line formulas for (e) propyl amine, (f) trim ethylamine, and (g) ethyl isopropyl-methylamine.
