Assuming the given compound is planar, it is to be determined and explained whether it is aromatic , antiaromatic, or nonaromatic. Concept introduction: Electrons can be resonance delocalized over a set of atoms that contribute conjugated p-orbitals to a single π system of molecular orbitals. For an acyclic conjugated system, the π electrons are the ones that can be shifted via resonance from one end to the other. Counting of the π systems and number of electrons is useful when a compound contains a triple bond. According to the MO theory, the two pi bonds are perpendicular to each other in a triple bond. Therefore, only one of those pi bonds can be conjugated with the neighboring π system.

Question

Using the graphs could you help me explain the answers. I assumed that both graphs are proportional to the inverse of time, I think. Could you please help me.

Shown below is the mechanism presented for the formation of biasplatin in reference 1 from the Background and Experiment document. The amounts used of each reactant are shown. Either draw or describe a better alternative to this mechanism. (Note that the first step represents two steps combined and the proton loss is not even shown; fixing these is not the desired improvement.) (Hints: The first step is correct, the second step is not; and the amount of the anhydride is in large excess to serve a purpose.)
