- How many chirality centers are there in the molecule shown below? How many stereoisomers are possible?Shown below is Streptomycin, an antibiotic medication used to treat a number of bacterial infections, including tuberculosis, plague, and endocarditis. Neomycin B has broad-spectrum antibacterial activity. Circle and label as many functional groups in these molecules as you can. Label each chiral carbon in Streptomycin. How many total stereoisomers exist for Streptomycin? Label each chiral carbon in Neomycin B. How many total stereoisomers exist for Neomycin B?(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?
- On b), I understand that we don't know which side of the molecule the Cl would attach on, but I was under the impression that we only show stereochemistry on a chiral center, and I do not see where the chiral center is on this molecule. Would you be able to explain this?-Sketch the Fischer projection and make a model of each stereoisomer (R and S) of the alcohol 2-butanol, CH3CHOHCH2CH3. Also sketch the monosaccharide glyceraldehyde, HOCH2CHOHCHO. Prioritize the four groups attached to the stereocenter with 1 being the highest priority and 4 being the lowest priority.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.
- Do you expect each boxed molecule to be chiral or not?Are the following compounds chiral ? Determine the configuration if it is chiral and draw the enantiomer, for each structure.Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. a. Do enantiomers have the same molecular formula? b. Does one structural formula represent both members of a pair of enantiomers? c. Are enantiomers stereoisomers?
- what is the chiral configuration at marked chiral centre? The left one is S and the right one is R but I don't understand how to decide itA trisubstituted cyclohexane compound is given below in its chair conformation. Draw the corresponding planar (overhead) representation, using wedge-and-dash bonds to indicate the substituent positions. Include the hydrogen atoms on the chirality centers (asymmetric carbons). Be sure that both wedge/dash bonds are drawn on the outside of the ring, or else the stereochemistry may be interpreted as square planar.In the previous problem, you saw that there were two chiral carbons in 4-bromo-3-hydroxypentanal. That molecule is drawn below with the chiral carbons circled. What is the maximum number of stereoisomers that can exist for this molecule? Can you help me, please? Can you explain to me?
