- Compound W shows stereoisomerism. Why are such isomers formed in approximately equimolar quantities no matter the synthetic pathway used for the preparation of the compound?(a) Draw all other stereoisomers of the molecule , labelling meso forms (if any), and assign descriptors to chiral carbon atoms. (b) Including molecule below, label pairs of enantiomers and pairs of diastereomers. (c) If you were to distill a mixture of all the isomers, how many fractions could be obtained, and what is in each fraction?In the molecule in the image: i) indicate how many stereogenic centres there are and if the molecule is overall chiral or not ii) assign the appropriate stereodescriptors to the molecules
- Draw all the stereoisomers for structures A and B, label each structure as chiral and achiral and give the type of isometric relationship to the original compound be as specific as possible.The instructions are to match the labels into their appropriate bins. I just need more explanation. Compound A and Compound C have the same kind of groups attached connectivity) but are not mirror images. So does that mean they are diastereomers? The same with compound E and F. What qualifies them to be meso compounds?For the following molecules: a. How many stereogenic centers are present? b. How many stereoisomers are possible for these molecules?
- By considering the stereochemical requirements for E2-elimination, and using an appropriate illustration need help indicating whether the more stable conformer (conformer B) of trans-1 can undergo E2 elimination. Thank you :)Chiral alcohols can be converted to chlorides by several pathways. Which is the best way to make the chloride with retention of configuration?And also what is the best description of the product(s) that form? Is it a single enantiomer, achiral product, pair of enantiomers or pair of diastereomers?
- up an example (not appearing in this ChemActivity) of a pair of molecules that are a)constitutional isomers, b) conformers. c) configurational stereoisomers.A mixture contains equal amounts of compounds A–D. a.Which compounds alone are optically active? b. If the mixture was subjected to fractional distillation, how many fractions would be obtained? c.How many of these fractions would be optically active?What allylic alcohol and DET isomer are needed to make each chiralepoxide using a Sharpless asymmetric epoxidation reaction?
