Draw the structure of the major product of each step in the
following three-step synthesis. As a start, one benzene ring is
drawn for you in each product.
5. Grignard Mechanism. Draw the major product for the Grignard reaction below in the box. Then, draw the proper FULL electron-pushing mechanism for the reaction, including ALL intermediates (with formal charges) and electron pushing arrows. Label the Electrophile and Nucleophile in each step! 1. BrMg 2. H2O+
Draw the structure of the major product of each step in the
following three-step synthesis. Show the formal charges, where
applicable. As a start, the benzene ring is drawn for you in each
product.
to a. Provide the mechanism for its reaction with HCl and give the major product(s), including stereochemistry. Give a BRIEF explanation for why this mechanism follows Markovnikov or anti-Markovnikov addition. b. Provide the mechanism for its reaction with Br2 in water solvent. Give the structure of the major product(s), including stereochemistry. For each step of your mechanism, identify the Nu- and the E+.
For questions 1-4, provide the missing reactant(s), reagent(s), or major organic product(s) of each reaction. Only one type of species is missing for each reaction. If you are providing reactant(8) or product(s), be sure to indicate stereochemistry if it is relevant. If you are providing reagents and more than one step is required, be sure to number each step. 1. EtMgBr 2.H20 NH [H] 5. Propose an efficient synthesis for one of the following transformations. Please circle the synthesis you...
For each addition route of the
reaction, draw the structure(s) of the major product(s), including
stereochemistry.
For each addition route of the reaction, draw the structure(s) of the major product(s), including stereochemistry
1. Provide a multiple step synthesis for the transformation
shown below.
2. Identify the carboxylic acid and alcohol needed to make the
ester shown below.
3. Propose a mechanism for the reaction shown below.
4. Show all the important resonance structures for the anion
shown below. Include arrows that show how to reach each form.
Indicate which resonance structure makes the greatest
contribution to the resonance hybrid and which resonance structure
makes the least contribution to the resonance
hybrid.

2. Propose a synthesis of each of the following molecules beginning with any alkyl halide and another neutral molecule. Choose your reagents carefully to try to favor a single mechanism (for example, charged versus neutral nucleophile/base). If you would like to use a charged molecule in your synthesis you should show the formation of that molecule from the neutral species. Pay attention to stereochemistry a. b.

Draw the structure of the product of each step in the following
three-step synthesis. Show the formal charges, if applicable. As a
start, the benzene ring is drawn for you in each product.Although the first step produces a mixture of isomers, the para
isomer is isolated as the sole product of interest and used in the
second step. Give only the major product for the second and third
steps.
