The mechanism for the following reaction occurs in a stepwise fashion. мол + он + но Draw the correct mechanism in the space below. Be sure to add lone pairs and charges to structures as needed. Ö Add/Remove step х он Click and drag to start drawing a structure.

Part A Draw a reasonable mechanism for this reaction. Interactive 3D display mode Ph Ph -P=CH, CH2 Ph 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 an atom or a bond and should end on an atom, bond, or location where a new bond should be created. D 5 C Q Q Q H x" iim H CI Br P F P Pearson

Draw the reaction mechanism for the following transformation given the starting materials, product,and reagents. Be sure to include all intermediates,curvy reaction arrows,and include any formal charges.

Determine whether the sollowing are SN1,SN2, E1, or E2 and draw the major product and if more than one can occur, then draw both products

1) Make sure to show all intermediates and reagents for the transformation shown below. OH

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 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

Fill out the table per instructions, I have attached two exact same pictures incase one is not visible, make sure to indicate the electrophile, major enolate, product separately and answer all questions. Thanks!

T 3. The first product made in an acid catalyzed hydration reaction of an alkyne is an unstable functional group called an enol. Enols quickly tautomerize to a carbonyl (either ketone or aldehyde). Starting with the enol, sulfuric acid, and water, draw the complete, detailed mechanism for this acidic tautomerization reaction below.
