Organic nitrogen chemistry
Atomic nitrogen, also known as active nitrogen, is highly reactive, being a triradical with three unpaired electrons. Free nitrogen atoms easily react with most elements to form nitrides, and even when two free nitrogen atoms collide to produce an excited N2 molecule, they may release so much energy on collision with even such stable molecules as carbon dioxide and water to cause … Witryna1 dzień temu · Nitrogen-containing small molecules are ubiquitous across the organic chemistry value chain, from commodity chemical feedstocks and synthetic intermediates 1 to agrochemicals, pharmaceuticals and ...
