Draw a valid and complete reaction mechanism for one (and only one) of the following reactions J, K, or L. Be sure to include any and all stereochemistry throughout the reaction mechanism. Include all appropriate steps, arrows, and electrons involved. Draw all of the intermediates (and/or transition states where discussed in lecture), and label all non-zero formal charges. For your reaction, also be certain to draw the starting material, the reactant(s), and all possible products. Please label these as "major" and "minor" (and "very minor," if needed). You may use a label more than once, but each structure should only have one label. Reaction J OH H,SO4, A Reaction K 1. PB13, 2. NaCN OH Reaction L HI, A

Choose one (and only one) of the reactions below and draw the complete mechanism for the major product(s) only, including the formation of the electrophile. You must also include all of the proper resonance structures for any intermediate species, but not for the starting material. Be sure to also include all arrows, charges, electrons, and any other mechanistic aspects discussed in lecture or within your textbook. Upload your answer (using any reasonable file format) within this question. Reaction I HO 1. AICI3 H 2. H-О H3C CI Reaction II H,SO4 NO2 Reaction III FeCl3 + Cl2 SO3H

answer questions 3 & 4 and all parts!! will be rating!!

Draw the curved arrow mechanism for the reaction between (2R,3S)-3,5-dimethylhexan-2-ol and PCl3. Note the specific instructions for each box. Include nonzero formal charges and lone pairs of electrons on all appropriate atoms. Then answer the question about the mechanism.

How do you do the Mechanism? Please do the Full Reaction so I can see whats going on also, dont forget the arrows and the intermediates and formal charges, because honestly I'm fully lost with this....

1 – Show the complete mechanism, using arrows to show electron movement, for the free radical chlorination of cyclopentane. The products are chlorocyclopentane and HCl. Be sure to include the initiation, propagation, and termination steps.

Curved arrows are used to illustrate the flow of electrons. Use the reaction conditions provided and follow the arrows to draw the intermediate and product in this reaction or mechanistic step(s). Include all lone pairs and charges as appropriate. Ignore stereochemistry. Ignore inorganic byproducts.

Predict the major products of this organic reaction. Draw only the major product or products in the drawing area below. If there's more than one major product, you can draw them in any arrangement you like. Be sure you use wedge and dash bonds if necessary, for example to distinguish between major products with different stereochemistry. If there will be no products because there will be no significant reaction, just check the box under the drawing area and leave it blank. Note for advanced students: you can ignore any products of repeated addition.
