- What aromatic product would you expect to obtain from oxidation of 1-chloro-2-ethylbenzene with potassium permanganate solution. Write the chemical name of the product as your answer. Show the reaction scheme and mechanismBromine reacts with alkenes in methanol according to the equation: - When this reaction was carried out with 4-tert-butylcyclohexene, only one isomer was formed with the molecular formula C12H23BrO (80% yield). Which of the following is the structure more reasonable for this compound?. Explain your reasoning through acorresponding mechanism.Draw the organic product obtained on treatment of each of the following two alkenes with bromine: (a) trans-2-pentene and (b) 1- methylcyclohexene. Having done this, draw the product of the reaction of these same alkenes with bromine in aqueous solution.
- Elimination of HBr from 2-bromobutane affords a mixture of but-1-ene and but-2-ene. With sodium ethoxide as base, but2-ene constitutes 81% of the alkene products, but with potassium tert-butoxide, but-2-ene constitutes only 67% of the alkene products. Offer an explanation for this difference.In an attempt to prepare propylbenzene, a chemist alkylated benzene with 1-chloropropane and aluminum chloride. However, two isomeric hydrocarbons were obtained in the proportion of 2: 1. What is the main product? How did this come about? Explain showing the mechanism and nomenclature of the reaction compoundswhy do (R)-3-chloro-1-methylcycloprop-1-ene and 5-Bromo-1,3-Cyclohexadiene react differently with cyanide (why doesn't cyanide pass through its usual mechanism for these two products and what did you obtain these specific products)
- Enamines normally react with methyl iodide to give two products: one arising from alkylation at nitrogen and the second arising from alkylation at carbon. For example, Heating the mixture of C-alkylation and N-alkylation products gives only the product from C-alkylation. Propose a mechanism for this isomerization.Reaction of -pinene with borane followed by treatment of the resulting trialkylborane with alkaline hydrogen peroxide gives the following alcohol. Of the four possible cis,trans isomers, one is formed in over 85% yield. (a) Draw structural formulas for the four possible cis,trans isomers of the bicyclic alcohol. (b) Which is the structure of the isomer formed in 85% yield? How do you account for its formation? Create a model to help you make this prediction.Using Halogenation in Synthesis Show how cyclohexane can be converted to cyclohexene by a stepwise sequence.
