- Q3. For the following reactions, predict the products, mechanism and name all the products obtained Catalytic hydrogenation of cycloalkenes. Reduction of cyclohexanone with Zinc amalgam (Zn/Hg alloy) in concentrated hydrochloric acid Addition of CH2I2 in an alkene in the presence of Zn-Cu 2-hexene + chlorine gas Halogenation of cyclohexane in the presence of light and catalyst Sulfonation of Cyclobutane with oleum Addition of HBr to methylcyclopropaneCompound A has molecular formula C4H10, and gives two monochlorides, B and C, on photochemical chlorination. Treatment of either of these monochlorides with potassium tert-butoxide gives the same alkene (C4H8) as the product, but B leads to just one isomer of the alkene, D, where C gives D and another isomer of the alkene, E. Treatment of monochlorides B and C with aqueous ethanol gives products F and G, respectively, both of which are of molecular formula C4H10O. What are the names of compounds A-G?Deduce the structure of each compound from the information given. All unknowns in this problem have molecularformula C8H12.(a) Upon catalytic hydrogenation, unknown W gives cyclooctane.

Propose a mechanism that accounts for both of these productsBased on the more stable conformation (conformation A), need help providing two mechanisms for the E2 elimination of the protonated version of cis-1 using a general base (B:) to give alkenes 2 and 3. Clearly show which hydrogens meet the stereochemical requirements for E2-elimination Using Zaitsev’s rule, indicate which is favoured. Pictured is also a reaction mechanism to show what the alkenes 2 and 3 are. Thank you :)
- Suggest a detailed mechanism for the reaction below. Represent the product in the most stable conformation and also its stereochemistry (Identify stereogenic centers as R or S)Suggest a detailed mechanism for the reaction below. Represent the product in the most stable conformation and also its stereochemistry.The spirocyclic pentadiene derivative F shown below is converted stereospecificallyinto compound G on heating. The transformation involves two consecutive pericyclicreactions of the same type, and proceeds via compound H which is not isolated. Identify the type of pericyclic reaction occurring, and determine the structure ofcompound H.
- The reaction of butan-2-ol with concentrated aqueous HBr goes with partial racemization, giving more inversion thanretention of configuration. Propose a mechanism that accounts for racemization with excess inversion.(b) Under the same conditions, an optically active sample of trans-2-bromocyclopentanol reacts with concentrated aqueous HBr to give an optically inactive product, (racemic) trans-1,2-dibromocyclopentane. Proposea mechanism to show how this reaction goes with apparently complete retention of configuration, yet withracemization. (Hint: Draw out the mechanism of the reaction of cyclopentene with Br2 in water to give thestarting material, trans-2- bromocyclopentanol. Consider how parts of this mechanism might be involved in thereaction with HBr.)2-bromopentane, when treated with alcoholic KOH yields a mixture of three alkenes A, B and C. Identify A, B and C.
