- Provide the complete mechanism using Curved Arrow Formalism for the reaction of 1-chloro-1-methylcyclopentane treated with NaOMe in MeOH. If more than one product is formed, which is the major, minor, and very minor product? Is the reaction SN1, SN2, E1, or E2. I appreciate the help on this question.arrow_forward- Identify compounds J & K - Draw a curved arrow mechanism that accounts for the formation of J (take into account stereochemical considerations)arrow_forwardwhich newman projection displays the proper antiperiplanar orientation for an E2 elimination of the reaction sequence belowarrow_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_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_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
- Propose a curved arrow mechanism for the conversion of compound 2 to product B. (Draw the mostrelevant resonance form of the Wheland intermediate).arrow_forwardWhat is the product of the following [1,3] sigmatropic rearrangement, A or B?arrow_forwardPlease fill out for each reaction i.Fill in the missing starting materials, products, or reagents as necessary.If no reaction occurs, write "N.R." and explain why this is the case. ii. Label each transformation as SN1, SN2, or acid/base. iii. Indicate if the product is racemic or a single enantiomer.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?arrow_forwardList the following carbocations in each set in order from most stable to least stable:arrow_forwardOf the two molecules below select which molecule would be predicted to react faster via an E2 elimination.
