Concept explainers
Interpretation:
It is to be proved that
Concept introduction:
An atom and its mirror image are directly opposite each other on opposite sides of the mirror. An atom and its mirror image are identical distances away from the mirror. When the mirror is perpendicular to the plane of the page, dash-wedge notation in the mirror image is identical to that in the original molecule. A molecule is chiral if the mirror image considering every orientation possible does not superimpose with the original molecule.

- Please also point out where the chiral centers are.arrow_forwardchiral. If you were able to make another molecule that is a mirror image of the chiral molecule, the mirror image and the original molecule will be non-superimposable. i.e. the atoms surrounding carbon won't completely align. The lack of alignment of the suround atom makes the two molecules different from each other. The central carbon must be surrounded by 4 different groups. The chiral carbon is highlighted. CH;CH) CHICH2 CH3-C-CH2-CHy OH CH) miror The 3D structure of the above molecule focuses on the chiral carbon and the bond surrounding the chiral carbon. The molecule on the left is different from the molecule on the right (mirror image) because they are non-superimposable. H. CH3-C-COOH HOOC COOH CH NH2 NH2 mimor Answer the following questions: 1.

- Determine which of these are meso and non-meso.arrow_forwardAnalyze the structure of the two stereoisomers and then determine whether one or both of them is (are) chiral (s). Explain your reasoning.arrow_forwardIdentify any chiral centers within the 2 molecules and identify whether each molecule is chiral or archial. If it is chiral, explain whether you expect a single enantiomer or a mixture of enantiomers to be formed.arrow_forward

Answer question here 4. An experiment is performed were the specific rotation was determined to be +52° for the resulting isolation (note this is not the observed rotation). If the enantiomerically pure compound has a literature rotation of +97°, then what is the percent of each enantiomer in the isolated mixture? Answer question here 5. Can you determine the percent R and S from the information given in questions 4? Explain. Answer question herearrow_forwardAssign R or S configuration around the two chiral carbons in the following molecule. - clearly show the priorities of the groups attached to each chiral carbon and how this resulted in your assigned configurationsarrow_forwardwhat is the absolute configuration on each of the chiral centers.arrow_forward
