5. Predict the major organic products of the following reactions. Show all asymmetric carbons with wedgeldash notation (i.e., as shown in the starting material). If a reaction produces a racemic mixture, show only one of the enantiomers produced. Carefully note the requested reaction mechanism for each reaction.

3. Shown below are a series of reactions. Predict the major product for each of them. Remember, you will need to first decide whether the reaction occurs by an SN2, SN1, E2, or E1 before you can determine what the product will be. Label each as SN2, SN1, E2, or E1. Hint: First decide whether S2/E2 or S1/E1 is favored, and then decide whether the reaction pathway goes by a substitution or elimination reaction. SN2 / SN1 E2/E1 Na DMSO,rt...

Q5-Fill in the boxes with the productis), reactantis) or reagent(s) for the following reactions. Draw only the predominate regioisomer and indicate the stereochemistry where appropriate. If a racemic mixture is formed, you may indicate this using a wavy line mor mark the chiral center with an asterisk (), and write racemic in the box. You may also draw both enantiomers and write RACEMIC in the box. Indicate if the product resulted from Sy2, Sn1, E2, E1 in the dotted box...
will you please check the ones i did also. 12. (I pt each) Each of the following reactions gives a substitution product. lIdentify the major product in each case and indicate whether the reaction is likely to proceed via a bimolecular (Su2) or a unimolecular (S1) mechanism.

3. (continued) For each reaction, draw the structure of the major product(s) including stereochemistry where appropriate. Fill in the box below each arrow with the mechanism(s) that will be followed (SN1/E1, SN2, or E2). For SN1/E1 reactions, draw products for both. g) Сн,сн,он h) CH2O- Na CH3OH i) Me. Br A Eto Nat Me
