(i) (iii) a 1g a' a1 atu a ey t el alu a1 aig ail Complete the gaps. The diagrams above represent (not respectively) the molecular orbitals of BeH3 and CH4. The diagrams are not completed and are only schematic, the vertical energy scale is not comparable between the three illustrations. Based on the molecular orbital diagrams, fill in the blanks in the statements below. Diagram (i) corresponds to the molecule and diagram (ii) corresponds to the molecule. comparing the nrosted acidity of these species, it is expected that the amolecule is the best proton donor, while the molecule should be the weakest proton donor. Both and may act as lewis acids, as they have, respectively, available and orbitals. A proper comparison of the energies of these orbitals will suggest that should be a better lewis acid, as it is the molecule that has the in energies among the three. Both and can react as hydride, forming isoelectronic loops. If through the loses a proton, it will form a kind of c3v symmetry. this species can react with orbital (LUMO), forming a Lewis adduct that will also have C3v symmetry. a." es tz au a- e az" a lla, e 219 a' au tz anti-ligantes no-ligantes ligantes menor || HOMO LUMO maior angulares tetradricos trigonais piramidais trigonais planos lineares
