The hydrobrominationof 2-methyl-1-butene could theoretically lead to 2 different alkyl bromides; in practice only one product is formed. Draw the structure of both theoretical products, circle the one that is actually produced, and briefly explain whyonly one product forms.

Draw all possible alkenes that could be generated from an E2 elimination reaction of 3-bromo-3-methylhexane. Suggest conditions that can be used to make just one of the alkenes in a controlled manner (i.e., conditions that would lead to formation of just one alkene as the major product).
Rearrangements can occur during the dehydration of 1° alcohols even though 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, as shown in Equation [1]. Using this information, draw a stepwise mechanism for the reaction shown in Equation [2]. We will see another example of this type of rearrangement in Section 16.5C.

Show the expected stereochemistry for each of the case and each mechanism should give two distinct products and then describe the relationship of the products to one another.
The Wolff–Kishner reaction uses hydrazine (H2NNH2) and hydroxide (–OH) to reduce a carbonyl to the alkane. The first steps of the mechanism convert a carbonyl to a hydrazone in a manner similar to imine formation. Draw the mechanism arrows for the reaction from the hydrazone to the alkane. Be sure to add lone pairs of electrons and nonzero formal charges to all species.
2-butanol + NOx + hv (assume the carbon-hydrogen bond on the carbon adjacent to the carbonwith the alcohol group is the weakest) For each mechanism, provide the photolytic cycle, a source for hydroxyl radical (if needed) AND atermination step. You may stop when you have accounted for all radicals AND all VOCs are stable (i.e., ifformaldehyde is a product of your mechanism, you do not have to oxidize that molecule to).
