- The addition of water to aldehydes and ketones occurs rapidly, although it is not thermodynamically favored. What would be the product for the reaction above? Hint: Think of the self-ionization of water and the polarity of the carbonyl group.arrow_forwardFor the SN2 reaction, draw the major organic product and select the correct (R) or (S) designation around the stereocenter carbon in the organic substrate and organic product. Include wedge-and-dash bonds and draw hydrogen on a stereocenter. -CEN H CI Incorrect Assign the stereochemistry. The organic substrate and organic product are both (R). The organic substrate and organic product are both (S). The organic substrate is (S) and the organic product is (R). The organic substrate is (R) and the organic product is (S)arrow_forwardUsing 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. OH Ht Aarrow_forward
- Give specific organic reactions for halohydrin formation. Draw the skeletal or condensed structure of the organic starting material (substrate) and the major and minor products. Write the reagents involved on top and/or bottom of the reaction arrow and box them. Name the major and minor products by writing their IUPAC names under the structure and identify by indicating the major product or minor product enclosed in parenthesis under each name. Indicate if syn addition or anti addition and write it beside the reaction and encircle it.arrow_forwardGive specific organic reactions for hydroboration-oxidation. Draw the skeletal or condensed structure of the organic starting material (substrate) and the major and minor products. Write the reagents involved on top and/or bottom of the reaction arrow and box them. Name the major and minor products by writing their IUPAC names under the structure and identify by indicating the major product or minor product enclosed in parenthesis under each name. Indicate if syn addition or anti addition and write it beside the reaction and encircle it.arrow_forwardPlease answer this Can you give examples to explain Addition reactions-general characteristics Benzene rings do not reactthi like alkenes Remember, the electrophile adds to the less substituted carbon, and the nucleophile to the more substituted carbon. 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. The nucleophile (X-) then adds to the more substituted carbocation.…arrow_forward
- Curved arrows are used to illustrate the flow of electrons. Use the reaction conditions provided and follow the curved arrows to draw the intermediate and product of this reaction or mechanistic step(s). Include all lone pairs and charges as appropriate. Use wedges and dashes to indicate stereochemistry. Ignore inorganic byproducts.arrow_forwardCurved arrows are used to illustrate the flow of electrons. Use the reaction conditions provided and follow the curved arrows to draw the intermediate and product of this reaction or mechanistic step(s). Include all lone pairs and charges as appropriate. Use wedges and dashes to indicate stereochemistry. Ignore inorganic byproducts.arrow_forwardA 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.arrow_forward
