Concept introduction: The reaction between bromine and alkene proceeds via the formation of cyclic bromonium intermediate. The reaction of bromine in water is an anti addition on alkene. This is a regioselective reaction, the hydroxyl group adds to the more substituted carbon of the double bond.

- Draw the organic products formed when cyclopentene is treated withfollowing reagent. [1] CH3CO3H; [2] H2O, HO−arrow_forwardWhich of the following alkene reactions occurs with a complete cleavage of the C=C ( breaking both pi and sigma bond components) ? Select one: A. Alkene + H2O2 with catalytic amount of OsO4 B. Reaction of an alkene with KMnO4/OH- at room temperature. C. Treating the alkene with O3 gas, followed by reduction with Zn / H2O D. Reaction of an alkene with water (H2O) in the presence of a H+ catalyst.arrow_forwardAn alkene G (C6H12) reacts with cold basic KMnO4 to produce H (C6H14O2). Hydrogenation of Gproduces I (C6H14). Ozonolysis of G produces propanone (CH3COCH3) and propanal(CH3CH2CHO).a) Draw the structure of G, H, I.b) State the reagent(s) and condition for ozonolysis reactionarrow_forward
- Draw the products formed when each alkene is treated with BH3 followed by H2O2,HO−. Include the stereochemistry at all stereogenic centers.arrow_forward4. Compound A has the formula C 8H 8. It reacts rapidly with KMnO 4 to give CO 2 and a carboxylic acid, B (C 7H 6O 2), but reacts with only 1 molar equivalent of H 2 on catalytic hydrogenation over a palladium catalyst. On hydrogenation under conditions that reduce aromatic rings, 4, equivalents of H 2 are taken up and hydrocarbon C (C 8H 16) is produced. What are the structures of A, B, and C.arrow_forwardButanol is treated with H2SO4 and heat. Identify the reaction and give the product that can be formed from itarrow_forward
- When 2-pentene is treated with Cl2 in methanol, three products are formed. Account for the formation of each product (you need not explain their relative percentages).arrow_forwardWhat product is formed when D-Gulose is treated with a. CH3I, Ag2O b. The product in (a), then H3O+ c. The product in (b), then C6H5CH2Cl, Ag2Oarrow_forwardDraw the products formed when each alkene is treated with O3 followed by Zn, H2O.arrow_forward
- 2-bromopentane, when treated with alcoholic KOH yields a mixture of three alkenes A, B and C. Identify A, B and C. Which is predominant?arrow_forwardHydrocarbon A, C9H12 absorbs 3 equiv. of hydrogen to give B, C9H18 when hydrogenated over a Pd/C catalyst. Treatment of A with aqueous H2SO4 and Hg(II) gives two isomeric ketones, C & D. Oxidation of A with KMnO4 gives acetic acid and the tricarboxylic acid E shown below. Propose a structure for A.arrow_forward
