Concept explainers
(a)
Interpretation:
The appropriate curved arrows and the products for each set of reactants undergoing the coordination step are to be drawn. Lewis acid and Lewis base from the given reactants is to be identified.
Concept introduction:
In a coordination step, a curved arrow is drawn to show the flow of electrons from an electron-rich site to an electron-poor site to form a bond.
Since Lewis acid has an incomplete octet, it accepts the electron pair from a Lewis base, which is an electron rich species. Lewis base has an atom with partial or full negative charge and a lone pair of electrons.
(b)
Interpretation:
The Curved arrow notation for heterolysis step to regenerate the reactant is to be drawn.
Concept introduction:
In a heterolysis step, the bond to the substrate is broken and the bonding electrons become a lone pair on the leaving group.

- 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.)arrow_forwardHi I need help on the question provided in the image.arrow_forwardDraw a reasonable mechanism for the following reaction:arrow_forward
- Draw the mechanism for the following reaction: CH3 CH3 Et-OH Et Edit the reaction by drawing all steps in the appropriate boxes and connecting them with reaction arrows. Add charges where needed. Electron-flow arrows should start on the electron(s) of an atom or a bond and should end on an atom, bond, or location where a new bond should be created. H± EXP.
