- 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_forwardA compound X of molecular formula C7H14 when hydrogenated produces 2,4-dimethylpentane and when hydroborated the obtained alcohol is 2,4-dimethyl-1-pentanol. a. What is the structure of X? b. If X is reacted with H2O catalyzed by H2SO4, what product is obtained? Write the structure, give the name, and write the complete mechanism, step by step of this reaction, in such a way as to explain the formation of the compound (DO NOT FORGET THE CORRECT USE OF ARROWS!).arrow_forwardYou are required to synthesize 2-bromopentane from the reaction between an alkene with HBr. Which alkene, 1-pentene or 2-pentene, should you react with HBr in order to get 2-bromopentane? Give an explanation.arrow_forward
- 12.Use of KMnO, to effect oxidative cleave of the alkene J, C3H16, yields two fragments, one of which is butanoic acid and the other a ketone, Q. When J reacts with one molar equivalent of H-Cl, the alkyl halide K, C3H17CI, is formed. What are the structures of J, J, and Q? Write all the reactions, and show your reasoning.arrow_forwardAlkenes undergo an addition reaction with borane in tetrahydrofuran (THF). For the reaction below: BH3 THF (solvent) a Draw the structure of the major organic product. Use the wedge/hash bond tools to indicate stereochemistry where it exists. Use wedge and hash bonds ONLY when needed to show reaction stereochemistry. If the reaction produces a racemic mixture, just draw one stereoisomer. opy aste ChemDoodlearrow_forwardOzonolysis (O3 in CH2Cl2) of compound A under reducing conditions (Zn /acetic acid) gives formaldehyde, 2-butanone, and compound B.
