* Non superimposable mirror images Non superimposable and not mirhot images Identify Whether each frit of compounds are enantiomers! or diastereomers: Two of the chital centers do have opposite configurations. But there remains one chital center that has the some configuration in both
15 Enantiomers are? stereoisomers having non-identical mirror image configurations stereoisomers that do not have non-identical mirror image configurations stereoisomers having u mirror plane of symmetry achiral stereoisomers Which of the following structures represents a chiral compound? The correct IUPAC name for the following compound is:
apers Stereochemistry Part 1 hit oo n d o 1. Chiral compounds-compounds with non-superimposable mirror images. For a on-superimposable mirror images. For a C to be chiral (asymmetric), to be it must have 4 different groups. Place an asterisk on all asymmetric carbons, if present. CH3CH2CHCH3 CH3CH2OH CH3CH2CHCH3 CH3 CH3 NH2 CH3
Molecules that differ in configuration CANNOT be: a. stereoisomers b. cis-trans isomers c. chiral centers that are mirror images of each other d. enantiomers e. chiral centers that can be interchanged by rotation of a single bond
enatiomers are non-superimposable mirror images. true or false.
17. Which of the following statements is true? ado on dai Jal A) Achiral molecules usually contain a plane of symmetry B) With one tetrahedral stereogenic center, a molecule may or may not be chiral. C) With two or more stereogenic centers, a molecule is always chiral. D) Chiral molecules usually contain a plane of symmetry 18. Which of the following is the correct definition for a pair of enantiomers? A) A pair of stereoisomers that have a plane of...

questions 9 and 10 austereomers, stereoisomers that are not related as mirror images. 9. Take the new model you constructed in no. 8 and projects project it into a mirror. Construct a model of the image in the mirror. Are the two models superimposable (9a)? What term describes the relations the two models (9b)? Thus if we let these three models represent different isomers of tartaric acid, we find that there are three stereoisomers for tartaric aci form and a...
A. Enantiomers: Certain substances have the unique property of rotating the plane of plane-polarized light. Such light rotation is detectable with the aid of a polarimeter. In order for a molecule to be optically active it must be chiral. Chiral objects lack a plane of symmetry and are non-superimposable on their mirror images. A sp?- hybridized carbon atom can fulfill these requirements if all four of its substituents are different. 1. Methane a) Prepare a methane molecule and then substitute...
