Draw all of the possible stereoisomers of the compound shown. Group them as enantiomeric pairs, or indicate any meso compounds. Label all stereocenters with the absolute stereochemistry (R or S).

For the following molecules, draw all possible stereoisomers using line-angle formulas with wedge/dash notation. Label the stereocenters as R or S. Indicate which ones are enantiomers and which ones are diastereomers. (Remember: there are 2 stereoisomers possible for a molecule with n chiral centers) (A) (B) (C) (1 chiral center) Br OH (2 chiral centers) CI OH CH3 (3 chiral centers)

Draw the sold/dashed wedge structures (skeletal structure) for all stereoisomers of 3,4-dichloro 4-methylhexane. Label each structure with the proper R/S notation Label enantiomers and diastereomers

how are chemists able to change the stereochemistry of a drug? Like what kind of experiments are done to test if you have the correct stereoisomer ?

8) For each of the pairs of molecules drawn below, place letters in the corner boxes corresponding to all accurate descriptions of the relationship between the two molecules. a) b) c) HO F A enantiomers F all letters that apply H H OH Вад CI all letters that apply all letters that apply B diastereomers C different conformations of the same molecule D identical conformations of the same molecule E constitutional isomers F stereoisomers G different molecules H both are chiral I neither is chiral

Explain your answer. I have the solutions to the questions. The instructor has given us the answer key. I still don't get the professor's answers. It's only the second part of the problem.

Only typed answer with full explanation otherwise leave it

Several compounds are shown below. For each, make two models: one model of the compound as shown, and the other where each tetrahedral stereocenter is inverted. Compare the two models side-by-side to see if the model with the inverted stereocenter(s) is the enantiomer, or if it is identical to the original. Remember, you can rotate around o-bonds to place the molecule in the conformation with the highest symmetry. Is each compound meso or not? OH OH OH OH DOKOOK OH OH Compound 1 Compound 2 Compound 1's mirror image is identical to Compound 1 Compound 1's mirror image is the enantiomer of Compound 1 Compound 1 is meso Compound 2's mirror image is identical to Compound 2 Compound 2's mirror image is the enantiomer of Compound 2 Compound 2 is meso Compound 3's mirror image is identical to Compound 3 Compound 3's mirror image is the enantiomer of Compound 3 Compound 3 is meso Compound 4's mirror image is identical to Compound 4 Compound 4's mirror image is the enantiomer of Compound 4…

4. Draw all possible stereoisomers of the following compounds. Assign the appropriate absolute (R/S) or geometric (E/Z) configuration to each of the stereoisomers (or double bonds) and label pairs enantiomers, diastereomers and meso compounds. (a) CH3CHBRCHOHCH3 (c) CH3CH=C(Br)CH=CHCI (e) CH3CH₂CHOHCHOHCH2CH3 (g) OH НО... CI (h) H3C Br (b) CH3CHBRCHBRCH ₂Br (d) CH3CH(C6H5)CHOHCH3 (f) CH₂(OH)CH2-CH(OH)CH=CHOH CH3 (1) Br HS Br

HO CH3 a. Label with asterisks (*) all of the stereocentres in the molecule shown above. b. How many stereoisomers are possible? c. Draw the structures of one pair of enantiomers for the above molecule. (Hint: You should draw two structures using wedge and dashed wedge bonds.)
