The following Grignard reagents are desired: a) cyclohexylmagnesium bromide b) sec-butylmagnesium bromide but only alkenes are available as raw material. Write the reaction equations that lead to the desired products, including the reaction conditions. Remember that if it is about discrete steps you must make it clearly noticeable.
There are two isomeric cyclohexa-1,4-diene products when benzoic acid undergoes the Birch reduction (see Problem 25.24). (a) Draw the mechanism that leads tothe formation of the major product. (b) Will the Birchreduction of benzoic acid occur faster or slower than theBirch reduction of benzene itself? Hint: Is –CO2H anelectron-donating or an electron-withdrawing group?
Propose a mechanism for the following cycloaddition reaction. Classify the reaction using the [m + n] classifications for cycloadditions. Draw the bonding molecular orbitals and identify the type of bonding present (supra - supra, antaraantara, or supra - antara). Identify if this reaction would proceed thermally or photochemically.
The following questions ask you to choose which of the pair reactions shown has been correctly identified as faster. Choose all correct answers In the SN2 displacement by iodide of CH3Cl or of CH3OTs, CH3OTs reacts faster. In the SN2 displacement by acetate of bromoethane or bromocyclohexane, bromocyclohexane reacts faster. In the SN2 displacement by CH3CH2O- or by CN- on 2-bromopropane, CN- reacts faster. In the SN2 displacement by HC≡C- on bromomethane in benzene or in acetonitrile, reaction in acetonitrile goes faster.

When Br2 is added to buta-1,3-diene at -15 °C, the product mixture contains 60% ofproduct A and 40% of product B. When the same reaction takes place at 60 °C, theproduct ratio is 10% A and 90% B.) Propose a mechanism to account for formation of both A and B
An inexperienced graduate student treated dec-5-ene with borane in THF, placed the flask in a refrigerator, and left for aparty. When he returned from the party, he discovered that the refrigerator was broken and that it had gotten quite warminside. Although all the THF had evaporated from the flask, he treated the residue with basic hydrogen peroxide. Tohis surprise, he recovered a fair yield of decan-1-ol. Use a mechanism to show how this reaction might have occurred.(Hint: The addition of BH3 is reversible.)
