- Which of the following alkenes have the Z designation? Choose all that apply.arrow_forwardThe substitution reaction below forms two ehters (which are consitutional isomers). Please draw the structures of the 2 ethers formed. Are the ethers single enantiomers or racemic mixtures?arrow_forwardPlease don't provide handwritten solution ..... which of these alkenes can be a cis and trans-isomere?arrow_forward
- How To Assign the Prefixes E and Z to an Alkene ? discuss by steps ?arrow_forwardQuestion 5: Conformations The elimination shown below has a very large differenco in the rate of reaction that depends on the stereochemistry of the substrate. Please use chair conformations in the space below to explain the results shown in the box. Please provide a brief explanation of the observed reactivity difference in the second box. Chair conformations:arrow_forwardAlkyl halides undergo elimination reactions to produce alkenes by the reacting with strong bases as shown in the following reaction (see image). In general, compounds where the halogen is axial (axial position) are much more reactive than those in which they are in the equatorial position. Taking the above into account: a. Which of the following compounds would give a faster elimination reaction: cis-1-bromo-2-tert-butylcyclohexane or trans-1-bromo-2-tert-butylcyclohexane? Draw the corresponding structures and clearly explain the choice.arrow_forward
- up an example (not appearing in this ChemActivity) of a pair of molecules that are a)constitutional isomers, b) conformers. c) configurational stereoisomers.arrow_forwardReaction of this bicycloalkene with bromine in carbon tetrachloride gives a trans dibromide. In both (a) and (b), the bromine atoms are trans to each other. However, only one of these products is formed. Which trans dibromide is formed? How do you account for the fact that it is formed to the exclusion of the other trans dibromide?arrow_forwardWhich group in the following pair is assigned the higher priority in R,Snomenclature −CH2Cl, −CH2CH2CH2Brarrow_forward
- A difficult problem in the synthesis of PGF2α is the introduction of the OH group at C15 in the desired conguration.a. Label this stereogenic center as R or S.b. A well known synthesis of PGF2α involves reaction of A with Zn(BH4)2, a metal hydride reagent similar in reactivity to NaBH4, to form two isomeric products, B and C. Draw their structures and indicate their stereochemical relationship.c. Suggest a reagent to convert A to the single stereoisomer X.arrow_forwardThe image below shows a permitted cycloaddition reaction.?arrow_forwardDraw the missing structural formulas (A,C,D,E and F), and the isomer of B. Also explain which would be the major product and why for B.arrow_forward
