Suggest typical reagents needed to convert an alkene into an aldehyde (e.g. B to C). Your answer may be written using either words and/or combinations of appropriately formatted chemical symbols. If more than one step is needed, then this must be indicated as follows: 1) NaCl, 2) H₂O Answer: Check B X² X₂ Stel tipiese re alkeen na 'n a antwoord kan kombinasies simbole. As m soos volg aam

When ethoxybenzene is treated with a mixture of nitric acid and sulfuric acid, two products are obtained, each of which has the molecular formula C8H9NO3. For the mechanism, draw the curved arrows as needed. Include lone pairs and charges in your answer.  Do not draw out any hydrogen explicitly in your products. Do not use abbreviations such as Me or Ph.

a) Show the structure of the reagent needed for this transformation and the mechanism for its synthesis using Ph3P and BuLi. ? CH₂ b) Show the mechanism for the reaction in (a) using the reagent that you provided.

The answer choices for part b ["How would you convert the alkene to a epoxide?"] are: (a) Br2/NaNH2 in liq NH3; (b) mCPBA; (c) OsO4Thank you!

Upon hydration of 2-heptyne in the presence of HgSO4 and H2SO4, the two carbons of the triple bond are similarly but not identically substituted resulting in two regioisomeric enols, each of which gives a different ketone. Supply the names of the two enols formed.

A carbamate can be prepared by treating an isocyanate with an alcohol, as shown here. This type of reaction is used to synthesize polyurethanes- polymers that have a wide variety of industrial applications, such as surface sealants, high-performance adhesives, and synthetic fibers. Propose a mechanism for this transformation. R'—ОН R. `N=C=0 R. OR' An isocyanate A carbamate (Substituted urethane) O=C

47) Provide the structure of the major organic product which results in the following reaction. CH₂ Br KI 48) When 1-iodo-1-methylcyclohexane is treated with NaOCH2CH3, the more highly substituted alkene product predominates. When KOC(CH3)3 is used instead, the less highly substituted alkene product predominates. Offer an explanation.
