This PhD thesis is in two parts, the first part is devoted to the design and developing a basic understanding of structure and chemical composition dependencies of gas transport, whereas in the second part a fundamental relationship between structure to the fire-retardant properties is established. pentan-2-amine. Illustrated Glossary of Organic Chemistry Amine: A functional group characterized by a C-N single bond that is not contained within another functional group. I know there is a NH2 in an amine structure, but this only has NH? and dimethyl means there a 2 identical single side chains right? but where on the skeletal structure are they? I'm totally stuck as to how the skeletal structure is supposed to look. Amines and amides are two types of compounds found in the field of organic chemistry. Amines are basic in nature, and in most of the reactions they act as nucleophiles.
