Interpretation:
The resonance structure for each compound is to be represented by curved arrows, which is considered as a guide to placing the electrons.
Concept Introduction:
In resonance structures, the electrons can move in order to help stabilizing the molecule and, the compound should have same number of electrons. Movement of electrons is shown by curved arrows in the compounds.
In a molecule, addition of nonbonded electrons and number of bonds is subtracted by the valence electrons on atom, this is known as formal charge.
The rules for drawing resonance structures are as follows:
Only nonbonding electron pairs and pi electrons can participate in conjugation in the formation of various resonating structures.
The single bonds present in the molecule do not break or form in the resonance structures.
The placement of atoms present in the molecule remains fixed.
The octet of all atoms is completely filled.

- Draw the Michael Adduct and the final product of the Robinson annulation reaction. Ignore inorganic byproducts.arrow_forwardDraw the Michael adduct and final product of the Robinson annulation reaction. Ignore inorganic byproductsarrow_forwardPost Lab Questions. 1) Draw the mechanism of your Diels-Alder cycloaddition. 2) Only one isomer of product is formed in the Diels-Alder cycloaddition. Why? 3) Imagine that you used isoprene as diene - in that case you don't have to worry about assigning endo vs exo. Draw the "endo" and "exo" products of the Diels-Alder reaction between isoprene and maleic anhydride, and explain why the distinction is irrelevant here. 4) This does not hold for other dienes. Draw the exo and endo products of the reaction of cyclohexadiene with maleic anhydride. Make sure you label your answers properly as endo or exo. 100 °C Xylenes ??? 5) Calculate the process mass intensity for your specific reaction (make sure to use your actual amounts of reagent).arrow_forward
