(1) Mechanism. Draw the mechanism explaining the following transformation of the reactant into the observed major product over this two-step reaction. Identify the structure of the mystery intermediate at the completion of Step 1 that must be accessed to make the final product after Step 2. Make sure to use appropriate arrow-pushing notation to depict the movement of electrons and bond breaking and formation. Show proper geometry, bond lengths, angles, etc. in each reactant, intermediate, and product. (16 pts) NaOEt...

CHE 230 F2019 Assignment 10 Student Name: ID Number: 10.W2S-1 Resonance structures of radicals: Draw two additional resonance structures for the molecule shown below. Be sure to show the curved arrows that demonstrate how you get from one resonance structure to the next. There should NOT be formation of partial charges in you structures. •H .U-I 10.W2S-2 When discussing radical reaction mechanisms we are concerned with bond strengths to make these mechanistic arguments. Which CH bond is the weakest in...
CHEM 2343A HOMEWORK W13 Name: DUE 11/18/19 at 9:10 AM There are total of 4 questions on this homework assignment 1. For the reaction outlined below in la and I draw out the reaction mechanism using arrow formalism to describe how the reaction below occurs. Be sure to draw out all action intermediates & the moment of all electrons needed to justify the formation of the indicand product. You do not need to add in any reagents that are not...
