(b)
Interpretation:
Major epoxidation product formed from X in the given reaction conditions needs to be identified
Concept introduction:
The alkene halogenation reaction is one in which a dihalide is added to a molecule after breaking the carbon-carbon double bond. The halide add to the neighbouring group from the opposite faces of the molecule. Whereas epoxidation is the addition of a single oxygen atom to an alkene to form an epoxide ring. The weak pi bond of the alkene is broken and two new C-O sigma bonds are formed. Epoxidation is typically carried out with a peroxyacid, resulting in cleavage of the weak oxygen-oxygen bond of the reagent.

- draw the two possible carbocations that can form when this alkene reacts with a strong acid (such as HBr or H3O+). of the two structures you drew, circle the more stable carbocationarrow_forwardIn halogenation reactions, why are halogens added on opposite sides of the compound? because the reaction proceeds via free radical and the pi cloud holding the electron are directed away from each other because of the formation of a halonium ion which sterically blocks one side of the compound thus the other side is open for attack because the halogen should occupy both sides to accommodate the pi clouds None of the above Two equivalents of HCl are added to an alkyne, where do you expect to see the Cl atom? The two Cl atoms will be distributed between the two Carbon atoms involved in the triple bond The two Cl atoms forms a bond with the less substituted carbon Both Cl atoms attach to one carbon, which is the more substituted one A mixture of products are formedarrow_forwardDraw the structures of two alkenes that would react to form the haloalkane below upon addition of HBr. Your alkenes should be different regioisomers that yield the haloalkane as the major product without requiring rearrangement to occur.arrow_forward
- How does the addition of NaNH2 to an alkane lead to the synthesis of a terminal alkyne? Doesn't the starting material have to be an alkene?arrow_forwardWhat is the major product of the reaction when the alkane reacts with Cl2 instead of with Br2? Disregard stereoisomers.. What is the anticipated percent yield of the major productarrow_forwardGive two examples each of Unsymmetrical alkenes and reagents and give two examples of reactions of alkenes that result in Anti-Markonikov’s addition productsarrow_forward
- so we know that fischer esterification is a type of organic reaction that involves the formation of an ester from a carboxylic acid and an alcohol in the presence of an acid catalyst. am I correct to assume that a fisher esterification mechanism would look different than the above nucleophilic addition reaction? If they are different you you present the Fisher esterification mechanism of the reaction of acetic acid with pentanol in the presence of an acid catalyst, sulfuric acid and explain the mechanismarrow_forwardIn free-radical substitution reaction of alkanes with halogens under uv light, the photolytic breaking of the halogen is the rate determining step. the formation of alkylradical is the rate determining step. the formation of halogen radical is the rate determining step. the abstraction of hydrogen from alkane by the halogen radical is the rate determining steparrow_forwardThe rate law for addition of Br2Br2 to an alkene is first order in Br2Br2 and first order in the alkene. Does this information suggest that the mechanism of addition of Br2Br2 to an alkene proceeds in the same manner as for addition of HBr? Explain.arrow_forward
- A. Without the use of H2 reductions or PCC oxidation fill in the blank steps of the reactions. Final products should be the major organic product.arrow_forwardWhat are the reagents used to convert 2-butyne to C4H8? What are the products when that C4H8 is mixed with OsO4, and H2O (the formula will be C4H10O2 racemic)? What is the product when C4H8 is mixed with RCO3H, and H2O (the formula will be C4H10O2 meso)?arrow_forwardExplain why alkenes undergo electrophilic addition reactionsand alkanes do not. Use Butane, But-2-ene and chlorine asexamples. Clearly show the reaction mechanism.arrow_forward
