(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?
Stereochemistry: Identifying Chiral Centers Indicate with an astrisk (*) each of the chiral centers in the following molecules:
Assign the absolute configuration to each chiral centers (signed with *).
assign the stereochemical configuration of the selected tetrahedral carbon chiral centers (R, S or N (not a chiral center)) and the alkene (E, Z or N (not a stereocenter)) that are indicated by the arrows (note that you do not have to assign the configuration of every chiral center in the molecule). If the atom in question is not a chiral center or is not a stereocenter circle N for neither.
A limited number of chiral compounds having no stereogenic centersexist. For example, although A is achiral, constitutional isomer B ischiral. Make models and explain this observation. Compoundscontaining two double bonds that share a single carbon atom are calledallenes. Locate the allene in the antibiotic mycomycin and decidewhether mycomycin is chiral or achiral.
Determine: The number and placement of the carbon chirality centers, if any. If this structure can have an enantiomer, why? What is the configuration of the highlighted carbon and how did you determine that?
could you explain the concept of chirality in organic chemistry? I understand what an enantiomer is, also diastereoisomers and meso.....but chirality is somehow not registering
Consider (2R,3R)-2,3-dioidobutane: (a)Draw a Fischer Projection of this structure with C1 on top and C4 on bottom. (b)Draw a Newman Projection of of the meso compound of 2,3-dibromobutane looking down the C2-C3 bondwith C2 in front, and label your asymmetric carbons as S or R.
How many chirality centers are there in the molecule shown below? How many stereoisomers are possible?
The following are representations of two forms of glucose. The six-membered ring is known to exist in a chair conformation in each form. Draw clear representations of the most stable conformation of each. Are they two different conformations of the same molecule, or are they stereoisomers that cannot be interconverted by rotation about single bonds? Which substituents (if any) occupy axial sites?
Following is a planar hexagon representation of L-fucose, a sugar component of the determinants of the A, B, O blood group typing. For more on this system of blood typing, see Chemical Connections: A, B, AB, and O Blood Group Substances in Chapter 25. (a) Draw the alternative chair conformations of L-fucose. (b) Which of them is more stable? Explain.
Build a model of methylcyclohexane, and use the model to complete the following Newmanprojections of methylcyclohexane in the chair conformation: a. When the methyl group is in an axial or equatorial (circle one) position, the molecule is inits lowest potential energy conformation. b. Label one Newman projection above anti and the other gauche to describe the relationshipbetween the methyl group and C3 of the ring. c. In general, which is a lower PE conformation, anti or gauche? d. Explain how your answer to b and c provide an explanation for why it is more favorable fora large group to be in an equatorial than an axial position.
