The energy of an electron in the first Bohr orbit of H atom is-13.6eV . The possible energy value(s) of the excited state(s) for electrons in Bohr orbits to hydrogen is(are):
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]
