(a)
Interpretation:
The molecular structure is to be drawn for the given name.
Concept introduction:
E/Z designations indicate the absolute stereochemistry of double bonds. An E designation indicates the higher priority groups on the double bond are on opposite sides of the bond. A Z designation indicates that they are on the same side of the double bond.
In cyclic compounds with less than eight atoms, a ring double bond can have only one configuration, with the ring continuing on the same side of the double bond.
The groups at each end of the double bond are assigned priorities on the basis of Cahn-Ingold-Prelog rules.

- Reaction 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_forwardDraw a detailed mechanism and give the products for the following Diels-Alder reaction. Label the Endo and Exo diastereomer.arrow_forwardCan you assit with confirming product(s), define major/minor, show stereochemistry, if appropriate, and/or if no reaction occursarrow_forward

Please indicate racemic if it is and if there is no reaction, please specify that as well. ?arrow_forwardFor each of the following: i) draw the structures of all product(s), both constitutional and stereoisomersarrow_forward
- Why does the diene need to be in the s-cis conformation to yield the cyclic product?arrow_forwardGive a full curved arrow mechanism for the ring-opening reaction of an epoxide in aqueousacid shown below. Show ALL non-bonded electron pairs and all non-zero formal chargeswhere applicable. (Note: you will need to redraw the structures provided in order to showthe mechanism correctly; non-bonded electron pairs have not been shown, although nonzero formal charges are included.) Be sure to show any stereochemical elements in theproduct(s) correctly.arrow_forwardFor each of the following, write the major product(s) and then draw out each step in the mechanism using curved arrows. Show ALL lone pair electrons and formal charges. Redraw ALL molecules as to show explicitly ALL bonds being broken or formed. Identify the molecular orbital (HOMO) of the nucleophile and the molecular orbital (LUMO) of electrophile involved in the nucleophilic attack. MO diagrams are not necessary..arrow_forward
