A familiar radical reaction is combustion. The oxygen molecule is a stable diradical, best represented by O–O . Because spins of the electrons are parallel, this molecule is stable. While the ground state of oxygen is this unreactive spin-unpaired (triplet) diradical, an extremely reactive spin-paired (singlet) state is available. For combustion to occur, the energy barrier between these must be … Web20 hours ago · You can use an extreme close-up for a range of different subjects, from people to nature to food.
