This cycloaddition reaction involves sixteen electrons; hence, it must be suprafacial on one component and antarafacial on the other. Thus, it must be a [14s + 2a] or a [14a + 2s]
Consider the ground state of(Z= 24) . The numbers of electrons with the azimuthal quantum numbers,l=1 and 2 are, respectively: (1) 16 and 4 (2) 12 and 5
