In the following reaction, determine whether the alkyne has been oxidized, reduced, or neither. (Hint: First look at each carbon atom separately and then look at the net change for
the alkyne as a whole.) Try to determine the answer without calculating oxidation states and then use the calculations to see if your intuition was correct.
H2SO4, H2O
H9SO4
The first carbon atom (with two added bonds to O) has been oxidized and the second carbon atom (with two added bonds to H) has also been oxidized. Overall, the alkyne
has been oxidized.
The first carbon atom (with two added bonds to O) has been reduced and the second carbon atom (with two added bonds to H) has also been reduced. Overall, the alkyne
has been reduced.
The first carbon atom (with two added bonds to O) has been oxidized and the second carbon atom (with two added bonds to H) has been reduced. Overall, the alkyne does
not undergo a net change in oxidation state and is, therefore, neither reduced nor oxidized.
The first carbon…
A benzene ring alters the reactivity of a neighboring group in the so-called “benzylic” position, similarly to how a double bond alters the reactivity of groups in the “allylic” position. Benzylic cations, anions, and radicals are all more stable than simple alkyl intermediates. a) Use resonance structures to show the delocalization of the positive charge, negative charge, and unpaired electron of the benzyl cation, anion, and radical.
Using Zaitsev's rule, choose the most stable alkene among the following.
Draw out the structures of each of the options then select the correct answer.
Recall that Zaitsev's Rule is about alkene stability. The trend for this is similar to the
trend for carbocation stability. Either more or fewer groups on the alkene (and the
carbocation) make it more stable. This question is wanting you to remember if it's
more or fewer.
A) 1,2-dimethylcyclohexene
B) 1,6-dimethylcyclohexene
C)
cis-3,4-dimethylcyclohexene
D) They are all of equal stability according to Zaitsev's rule.
Provide the major dehydration product of the following reaction.
Recall which of the four substitution and elimination reactions a dehydration is.
Before you do your S# or EF mechanism, remember what heteroatoms do in the
presence of an acid (aka-the-OH is a bad leaving group, but protonating it might
turn it into a good one).
Don't forget to apply the concept from the previous question.

Markovnikov’s Rule: The addition of a hydrogen halide to an alkene favors the product in which the proton adds to the alkene carbon that is initially bonded to the greater number of hydrogen atoms. Carbocation rearrangements- Methyl groups and hydride groups can migrate to make a more stable carbocation. A primary carbocation is less stable than a secondary carbocation, which is less stable than a tertiary carbocation. Addition of A Strong Bronsted Acid Hydrohalogenation HX addition to an alkene. Goes through a carbocation intermediate. The electrophile (H+) adds to the less substituted carbon, and the carbocation forms on the more substituted carbon.

Although in reality, all poppies produce opoids, the drug “morphine" , codeine as well as other opioid pain killers are typically derived from opium. A quick way to find or identify these compounds is to look for a six-membered ring containing a nitrogen. Often, if you see a six-membered ring with a nitrogen, you have some sort of an opoid or a modified synthetic pain killer. With that said, morphine and codeine are typically not injected or given orally in pure form. Instead, their salts are used, such as morphine sulfate or codeine phosphate. Why are the salts used or administered instead of the pure substances (or non-salt forms)? (I am not interested in drug names, but to have you answer the why of this question.)
