Structure Clasification
Saturated hydronitrogens can be:
- linear (general formula NnHn + 2) wherein the nitrogen atoms are joined in a snakelike structure
- branched (general formula NnHn + 2, n > 3) wherein the nitrogen backbone splits off in one or more directions
- cyclic (general formula NnHn, n > 2) wherein the nitrogen backbone is linked so as to form a loop.
According to the definition by IUPAC, the former two are azanes, whereas the third group is called cycloazanes. Saturated hydronitrogens can also combine any of the linear, cyclic (e.g. polycyclic), and branching structures, and they are still azanes (no general formula) as long as they are acyclic (i.e. having no loops). They also have single covalent bonds between their nitrogens.

Famous quotes containing the word structure:
“I’m a Sunday School teacher, and I’ve always known that the structure of law is founded on the Christian ethic that you shall love the Lord your God and your neighbor as yourself—a very high and perfect standard. We all know the fallibility of man, and the contentions in society, as described by Reinhold Niebuhr and many others, don’t permit us to achieve perfection.”
—Jimmy Carter (James Earl Carter, Jr.)
