Interpretation:
The mechanism that accounts for the formation of the mixture of the products in a given reaction is to be drawn.
Concept introduction:
Electrophilic addition of the molecular chlorine into but-2-ene gives anti-addition of the molecular chlorine via the formation of the chloronium ion as an intermediate. Under similar conditions, molecular chlorine undergoes both syn and anti-addition to

- The bicyclo [3.1.0] hexane ring system, highlighted in compound 3, is found in several natural products, including sabinene, a compound partially responsible for the flavor of ground black pepper. One method for preparing this ring system involves the conversion of compound 1 to compound 2, as shown below. Draw the structure of compound 2 and provide a reasonable mechanism for its formation. Add any remaining curved arrows to complete step one of the mechanism, and modify the given drawing as needed to show the intermediate that is formed in this step.arrow_forwardConsider the following reaction scheme: (i) Identify compounds J and K. (ii) Draw a curved arrow mechanism that accounts for the formation of J [please make sure your mechanism takes into account stereochemical considerations]. please can you show how you decide the stereochemistryarrow_forwardGiven that an E2 reaction proceeds with anti periplanar stereochemistry, draw the products of each elimination. The alkyl halides in (a) and (b) are diastereomers of each other. How are the products of these two reactions related? Recall from Section 3.2A that C6H5 −is a phenyl group, a benzene ring bonded to another group.arrow_forward
- Given that an E2 reaction proceeds with anti periplanar stereochemistry, draw the products of each elimination. The alkyl halides in (a) and (b) are diastereomers of each other. How are the products of these two reactions related? Recall from Section 3.2A that C6H5– is a phenyl group, a benzene ring bonded to another group.arrow_forwardComplete the following reactions by providing the missing product(s). Determine what mechanism operates in each case (SN1, SN2, E1, or E2). Show the stereochemistry of the product(s) where appropriate. If more than one product is formed circle the major one.arrow_forwardDraw the major organic product for the reaction of this compound with PBr3. What type of mechanism is involved in this transformation?arrow_forward
- Complete the reactions given below, write down the type of mechanism (SN1, SN2, E1, E2)?arrow_forwardWhat are the products obtained (2 stereoisomers A and B) when (Z)-hex-3-ene is treated with Br2 in anhydrous medium? Show the mechanism of this reaction. When the dibromide formed is treated with KOH in EtOH, only (Z)-3-bromohex-3-ene. Explain this result and justify why the E isomer cannot be obtained here. here.arrow_forwardBetween E1 and E2, which reaction mechanism is most efficient to synthesize the (E) stereoisomer of this product on an industrial scale?arrow_forward
- (a) Give a mechanism for this reaction, showing how the two products arise as aconsequence of the resonance-stabilized intermediate.(b) The bromination of cyclohexene using NBS gives only one major product, as shown onthe previous page. Explain why there is no second product from an allylic shift.arrow_forwardCan you answer it and explain it? State the mechanism in which through reaction proceeds sn2 or sn1arrow_forwardWhen an unsymmetrical Alkenes such as propane is treated with N-bromosuccinimide in aqueous dimethyl sulfoxide, the major product has the bromine atom bonded to the less highly substituted carbon atom. Is this Markovnikov or non-Markovnikov orientation? Show its complete reaction mechanism.arrow_forward
