- How would the molecular orbitals of cyclopenta-1,3-diene, the carbocation, carbanion, and the radical differ? Drawings would be appreciated! Thank you in advance.Predict the products of halogenations, oxidations, reductions, and cleavages of alkenes, including the orientation (regiochemistry) and the stereochemistry of the reaction.Which is more stable - a phenyl radical, [C6H5]•, or a benzyl radical, [C6H5CH2]• - and why?
- Determine all of the products obtained from the addition of HCl to the 1,3-diene. Once determined, draw a mechanism that accounts for the formation of every product. Then, Identify and account for the formation of the major adduct/or adducts under these conditions assuming that the reaction is conducted under thermodynamic conditions.Provide Examples of dehydrohalogenation of dihalides to afford alkynes ?Predict the products of additions, oxidations, reductions, and cleavages of alkynes, including the orientation of the reaction (regiochemistry) and the stereochemistry.
- Free-radical chlorination of hexane gives very poor yields of 1-chlorohexane, while cyclohexane can be converted to chlorocyclohexane in good yield. How do you account for this difference?Treatment of the diene shown with excess ozone followed by a reductive work-up produces.predict the product of each of the following reactions. Mono-halogenated products only for any radical halogenation reactions.
