Reaction of HBr with 3-methylcyclohexene yields a mixture of four products: cis-and trans-1-bromo-3-methylcyclohexane and cis-and trans-1-bromo-2-methylcyclohexane. The analogous reaction of HBr with 3-bromocyclohexene yields trans-1, 2-dibromocyclohexane as the soleproduct.
Draw structures of the possible intermediates, and then explain why only a single product is formed in this reaction.
1-Write the reaction of acidic water with the followings:
a-1-Methylcyclopentene
b-1-ethyl-3-methylcyclohexene
c-isobutene
2.Draw and name a cyclic alkyne withasix membered ring.
Products: 1-methylcyclohexene, 3-methylcyclohexene,
methylenecyclohexane
1a) Which kind of mechanism can better account for the product
mixture obtained from the dehydration of cis and trans
2-methylcyclohexanol: E1, E2, or a combination of the two? [Keep in
mind that the actual mechanism may be none of these.]
b) Write detailed mechanisms explaining the formation of all the
observed products.
In step 4 of glycolysis,
fructose-1,6-bisphosphate is split into two three carbon products.
One product has an aldehyde function; the other has a ketone
function. Step 5 isomerizes the ketone to the aldehyde
Circle
the aldehyde group.
Steps 1 through 5 represent the first
half of glycolysis. How many molecules of
glyceraldehyde-3-phosphate are produced per glucose in the first
half of glycolysis?
Which set of conditions would favor glycolysis in the reaction
of fructose 6-phosphate and fructose 1,6-bisphosphate?
1. high concentrations of ATP, Cirate and hydrogen ion
2. low concentrations of ATP, Cirate and hydrogen ion
3. high concentrations of acetyle CoA
4. low concentrations of glucose
