g. Draw the Snl mechanism of the reaction between 2,5-dimethyl-2,5-hexanediol and hydrochloric acid (excess). Show lone pairs, electron pushing arrows, 3-D view to reflect appropriate stereochemistry, reactants, intermediates, and products. You do not have to show transition states. Name the product. Draw and completely label a reaction energy diagram corresponding to the mechanism you have drawn.
The chromate and manganate esters shown below form from the
reaction of 3-butene-2-ol with chromic acid and manganese dioxide
(MnO2) respectively. They both decompose to give methyl
vinyl ketone through mechanistically distinct pathways. (a) Provide
the mechanism of the manganate ester decomposition and (b) indicate
which intermediate in your mechanism rationalizes the observation
that only allylic and benzylic alcohols react with MnO2
to give carbonyl products.

products. name the product. draw and completely label a reaction
energy diagram corresponding to the mechanism you have drawn.
B. Draw the Snl mechanism of the reaction between (R)-3-bromo-3-methylhexane and ethanol. Show lone pairs, electron pushing arrows, 3-D view to reflect appropriate stereochemistry, reactants, intermediates, and products. You do not have to show transition states....
Give the name of the alkene shown below. Show the mechanism of the reaction below. Identify all intermediates and the product. Give a specific reason as to why the product is optically inactive. н-Вr н НС CH3 raw the mechanism for the reaction of I-Br with 1-methylcyclohexene showing all intermediates and oduct with proper stereochemistry. Explain why the product is optically inactive.
1. Give the complete reaction mechanism for the acid catalyzed hydration if 3,4-dimethyl-1-butene showing all intermediates and products. (10 pts).
draw curved arrows
Draw curved arrows to complete the Diels-Alder mechanism for the two reactants shown. Then draw the product of the reaction in the box to the right. Do not show stereochemistry.
Complete the electron-pushing mechanism for the E1 reaction when
2-methylbutan-2-ol is treated with 20% sulfuric acid.
Hint: The E1 mechanism involves dissociation of the hydroxyl
group from the substrate. The acid is used to convert the hydroxyl
group to a good leaving group. Do not delete any pre-drawn
bonds/charges/lone pairs.
