- The Favorskiireaction involves treatment of an a-bromo ketone with base to yield a ring-contracted product. For example, reaction of 2-bromocyclohexanone with aqueous NaOH yields cyclopentanecarboxylic acid.what is the mechanism of the reaction.Provide a mechanism for the following isomerization in aqueous acid. Thank you in advance!Provide a stepwise synthesis for benzyl chloride to benzyl alcohol with reagents Na2CO3 and H2O (including arrow-pushing mechanisms) Kindly show all the arrow push
- Devise a synthesis of the ketone hexan-3-one, CH3CH2COCH2CH2CH3, from CH3CH2Br as the only organic starting material; that is, all the carbon atoms in hexan-3-one must come from CH3CH2Br. You may use any other neededreagents.a) Write out the first 3 steps only(to the tetrahedral intermediate shown) in the 6-step arrow pushing mechanism showing how ethyl propanoate is hydrolyzed in acid to form propanoic acidand ethanol. b) NaOH/H2O also serveto hydrolyze an ester; briefly explain why NaOH/H2Ois generally preferable.Compounds A, B, and C have the same molecular formula C4H8. They all react wotu H2/PtO2 to give the same compound. The reaction of A or B with H2O/H2SO4 or with BH3-THF, followed by treatment with a basic solution of hydrogen peroxide, gives the same compound, namely D. The reaction of C with H2O/H2SO4 also gives D. However, the reaction of C with BH3-THF, followed by HO-, H2O2 gives a new compound, E. Provide the identity of A, B, C, D, and E along with explanations of reactivity.
