Q3- Fill in the boxes with the product of the following reactions. Draw only the major product or products and indicate stereochemistry. When a racemic mixture is formed, you must draw both enantiomers and write racemic in the box. A) B) NBS hv NBS hv C) NBS hv D) CH3 Br2 hv E) F) NBS hv Br2 hv

Draw the major products.  Indicate stereochemistry where relevant.

Draw the products of these reactions clearly showing stereochemistry in each case if necessary. If the product is formed as a racemic mixture, clearly draw one stereoisomer with dash/wedge bonds and write “+en”. Circle whether each reaction occurs by an SN1 or SN2 pathway.

A4. please draw the starting materials for the following cycloadditions/ rearrangements. make sure to show the correct stereochemistry please

Draw the products for the following chemical reactions, indicating stereochemistry wherever applicable. Indicate if the reaction proceeds via SN1 or SN2 mechanism

Draw mechanism arrows and then predict the major products and stereochemistry. Also include the labels of thermodynamic and kinetic  no stick structure don't understand  3,4-dimethylhex-3-ene with BH3. After reaction is complete, add H2O2, –OH, and H2O

Select the true statement below, regarding the reaction provided. Options:   The Br2 reagent does not add two bromines across an alkene.   The dibromo product shown is meso.   The dibromo product does not have the correct stereochemistry.   The Br2 reagent adds two bromines "syn" across an alkene.

What starting material or product is missing. Show stereochemistry and mechanism.

For the following reactions:  A. Draw the missing reactant, reagent or product including the correct stereochemistry where appropriate. B. Determine the Reaction Pathway (Sn1, Sn2, E1, E2) leading to the desired product C. How many steps are in the Reaction as can be plotted on a Reaction Coordinate?

Fill in the missing structure(s) for the reaction pathways shown below. Provideall starting material(s), reagent(s), or product(s). If more than one product can beformed, draw all major products. If more than one starting material or reagent ispossible, write all starting materials or reagents. Include stereochemistry in youranswer, if applicable, and draw all stereoisomers. Don't forget about resonance.
