A. Draw (trans)-4-methylhex-2-ene, which is the desired major product. B. Assuming dehydrohalogenation, there are two possible substrates that could give you that product; draw and name them both. C. For each substrate give the best mechanism and reagent and explain your choice
if possible , could you draw a mechanism to explain it

3. There are two possible substitution products fr products and a complete mechanism for their for IUPAC system and circle the major product. Ustitution products from the reaction of 3,3-dimethyl-2-butanol with aq. HBr. Draw the mechanism for their formation, including all intermediates. Name both products based on the :OH MW: 102. Ts-gimo 4. Based on the reaction above, calculate the theoretical yield for the reaction based on 2.0 g of the 3,3-dimethyl-2- butanol and 5 mL of the 48% HBr....
D. (4 pts) Hydroboration of 1-methylcyclopentene (1) is regioselective, trans-2-methylcyclopentyl borane (2) is the major product. Draw two transition state structures for the hydroboration of 1 in the boxes provided that account for each alkyl borane 2 & 3. Use dotted lines (-----) to indicate partial bond formation and partial bond cleavage. Indicate partially positive and partially negative atoms with delta signs (+ & 6-).

Look up and draw the mechanism for the addition of Br2 to
double bonds. Reference the source from which you acquired the
mechanism.
Give the IUPAC name of the major product in the above-mentioned
reaction.
Draw the major product of obtained in the addition of Br2 to
stilbene.
Is this isomer chiral? What would be the optical rotation if
this sample was placed in a polarimeter?
Would a student obtain the same product if you started with
cis-stilbene instead of...
