Add THREE curved arrows to draw the first step of the racemization mechanism. Modify the given drawing of the product as needed to show the intermediate that is formed in this step, with the appropriate stereochemistry of the methyl group indicated. Use the +/-tools to add/remove charges, and use the single bond tool to interconvert between double and single bonds. 2C%

#6).  Second picture shows instructions on how the arrows must be shown as.

Draw the products of the two step reaction sequence shown below. Use a dash or wedge bond to indicate stereochemistry of substituents on asymmetric centers. Ignore inorganic byproducts. НО. 1. NaCN 2. H₂O OH ………. Select to Edit Q

H2SO4 CH3CH2OH a. Draw the structure of the tetrahedral intermediate INITIALLY FORMED in the reaction shown. • You do not have to consider stereochemistry. • Do not include counter-ions, e.g., Na", I', in your answer. • In cases where there is more than one answer, just draw one. ору aste

Substitution and elimination: predict the product Maximum allowed tries per question: Unlimited (7) Draw the major organic product of the reaction. Follow this procedure: determine whether the reaction conditions are acidic or basic; identify the most nucleophilic/basic atom, the electrophilic atom, and the leaving group; predict whether elimination or substitution will occur; and then draw the product. Indicate the stereochemistry at every stereocenter with a single wedged (up), hashed (down), or wavy (a mixture of up and down; either) bond.

Curved arrows are used to illustrate the flow of electrons. Using the provided starting structure, draw the curved electron-pushing arrows for the following reaction or mechanistic step(s). Be sure to account for all bond-breaking and bond-making steps. Then draw any missing organic intermediates or products for this reaction. Include all lone pairs in the structures. Ignore inorganic byproducts and counterions.

For the dehydration shown, use curved arrows to show the formation of the carbocation intermediate in the presence of sulfuric acid H, SO,, then draw the structures of the minor and major products of the elimination. 4 H2SO4 Major and Minor products HO: The H, SO, is abbreviated as H* in the drawing module. Do not delete any pre-drawn bonds, charges, or lone pairs. If you 4 accidentally make a mistake, remove the last change by using the undo button on the lower left or revert the drawing palette to the original state by selecting the More menu, then select Reset Drawing. Step 1: Use curved arrows to complete the Step 2: Use a curved arrow to show the protonation mechanism of the alcohol. formation of the carbocation intermediate for the elimination.
