Can someone please help me with this exercise? Label each stereocenter above as R or S....
Assign R/S configurations to each chiral center in the following molecules. Clearly label the stereocenter and show your priority ranking. If no chiral centers exist, write "achiral." (15 pts) GEHICH ANTICHE VSH он "CH, HjC NH2 OH
R / S stereocenters
8. Try R 1 S stereocenter! Label each group on the stereocenter as 1, 2, 3, or 4. First look at the 4 atoms directly bonded to the stereocenter (chiral carbon). For tiebreakers, use the 3 bonds (other than bond to stereocenter) that are on each of the "tied" carbons. 4 atomsTiebreaker Rank (3 other bonds) Br Once you have rankings, Make sure #4 is pointed away, then see which direction the 1 to 2 to...
1. (23 pts.) Label each stereocenter (chiral center) as Ror S. Label each molecule as chiral or achiral. CH ен-он H- CH3 . Он CH2OH Сн,он h) н он В ньон нон НО-Б-н ен,он но- н H-LOH CH OH
5-26 For each structure, 1. star (*) any asymmetric carbon atoms. 2. label each asymmetric carbon as (R) or (S). draw any internal mirror planes of symmetry. label the structure as chiral or achiral. label any meso structures. We were unable to transcribe this image
please solve all the questions
5. Label the chiral carbon(s) in each of the following structures with an asterisk (*). H OHH OH H-C-C=C – H | H H OH 6. Use your knowledge of the Cahn-Ingold-Prelog sequence rules to rank the substituents in order of priority, highest priority first: HO HO The alcohol The chlorine The ethyl group The carboxylic acid group 7. Identify the following as chiral or achiral. If chiral, identify the chiral carbon(s) with an asterik...
please label clearly
Stereochemistry: Choose the chiral structures Choose the chiral structures among the ones shown. Check all that apply. Stereochemistry: Choose the achiral structures Choose all the achiral compounds among the ones shown. (Each of your choices can be achiral in any conformation, not just the ones shown.) Check all that apply.
Please help me!!

1. (21 points) Is the following compound a meso-compound? If yes, show it in 3D in the box below using wedged and dashed bonds to indicate the substituent bond direction and draw the internal mirror plane of symmetry (if any). (3 points) HOOC-CHOH-CHOH-COOH Draw the 3D structures of the stereoisomers of the compound above. Use wedged and dashed bonds to indicate the substituent bond direction in each stereoisomer.
