In the box to the left of each reaction below, write the mechanism by which it occurs (could be SN1, SN2, or E1, or even 2 of them). Then draw the product(s).
Please fill out for each reaction i.Fill in the missing starting materials, products, or reagents as necessary.If no reaction occurs, write "N.R." and explain why this is the case. ii. Label each transformation as SN1, SN2, or acid/base. iii. Indicate if the product is racemic or a single enantiomer.
Could someone please help me with this two-part practice problem? A. Provide the missing reagent or product for each reaction below. Where necessary, indicate the stereochemistry of the starting material or products. Draw all stereoisomers of products that are formed. B. In reaction b above, what is the relationship of the stereoisomeric products? Would the stereoisomers be formed in equal or unequal amounts? Thank you!
For the dehydrohalogenation (E2) reaction shown, draw the Zaitsev product(s) resulting from elimination involving C2–C3 (i.e., the carbon atoms depicted with stereobonds). Show the product stereochemistry clearly. If there is more than one organic product, both products may be drawn in the same box. Ignore elimination involving C2 or C3 and any carbon atom other than C3 or C2.

1. What are products formed from the below reaction? 2. Draw the stereoisomers and name them. Hint: There are two different constitutional isomers and each constitutional isomer has 2nstereoisomers.
For the dehydrohalogenation (E2) reaction, draw the Zaitsev product, showing the stereochemistry clearly. You might find it helpful to make a model of the starting material to determine the correct conformation.
a.Draw three-dimensional representations for all stereoisomers of 2chloro-3-methylpentane, and label pairs of enantiomers. b. Considering dehydrohalogenation across only C2 and C3, draw the E2 product that results from each of these alkyl halides. How many different products have you drawn? c. How are these products related to each other?
Rearrangements can occur during the dehydration of 1° alcohols eventhough no 1° carbocation is formed—that is, a 1,2-shift occurs as the C—OH2+ bond is broken, forming a more stable 2° or 3° carbocation, asshown in Equation [1]. Using this information, draw a stepwisemechanism for the reaction shown in Equation [2]. We will see anotherexample of this type of rearrangement
Draw all the major products resulting from the reactions below, taking into consideration both the regioselectivity and stereoselectivity of the reactions. If pairs of enantiomers form, draw both enantiomers. (NOTE: for the second reaction, draw out the hydrogen.)
For this mechanism, why are there two E1 major products? Are both of the E1 products of equal stability? Why or why not? What is the relative stability of the cycloalkenes with methyl? Also, why doesn't SN1 have two products? Is it because shifting the hydride would make it less stable?
