1.Make a model of (2R)-2-bromobutane. You may omit the
hydrogens, except on the chiral carbon. Draw the structure, be sure
to show stereochemistry by using the wedged and dashed
lines.
a. Rotate the ethyl group 180o. Does this change the molecule from R to S? Why or why not?

1. Construct a model that has a central carbon atom with 4 different colored spheres attached to it, representing four different atoms or groups. Draw a solid/dashed-wedge structure of this model here and answer the following questions. ç (a blue ball) IND Fig. 1 B a. Does the model have a plane of symmetry? Yes No The central carbon is said to be a stereocenter, stereogenic center, or chiral carbon. Change one of the colored spheres so that two of...

Assignment 3: Chiral Carbons and Stereoisomers On a page titled Chiral Carbons draw using a chemical drawing program or other computer generated form the expanded structure of your molecule. No hand drawn structures will be accepted. O Determine if your molecule contains any chiral carbons. If there are chiral carbons in your molecule, circle or highlight all of them. If your molecule does not contain any chiral carbons explain why none of the carbons are chiral. One a...
rojection Formulas for each model in #16 (again orient the carbon chain up and down). Are the mirror images "superimposable?" Interchange any two of the groups located at one of the chiral centers on one of the models in # 1 6. What is the stereochemical relationship of the resulting structure with the one that used to be its mirror image? Will this 'new' model be "optically active?" Why or why not? 18.

Please help!! The molecule is Ventolin and i need to label all
of the functional groups, chiral carbons and illustrate how it
forms hydrogen bonds with water. The instructions are in the
picture as well as the expanded form of Ventolin. At the bottom of
each page it asks for a update. have to write 2-3 sentances
summurizing the major ilunderstamding.

4. Absolute Configuration and R/S Sequence Rules. In 3 you constructed models with two stereocenters that represented 4 stereoisomers. 2,3-Dibromobutanoic acid exemplifies such a compound, Make models for the isomers of this compound. a. Draw solid/dashed-wedge structures for the 4 possible stereoisomers and label the enantiomers and diastereomers. b. Specify the sequence priority for the substituents on carbon-2 and carbon-3. Label each structure with the proper R/S notation in the drawings above, for example (2R, 35). d. Draw Newman projections...

PART 3: 2,3-BUTANEDIOL CH-CH(OH)-CH(OH)-CH, mirror images, not superimposable Build as many models of 2,3-butanediol as you can. First, attach two carbons with a single bond. To each carbon add one carbon, one hydrogen, and one oxygen. To complete the structure, Ti the remaining hydrogen atoms. Remember, a model is not different if it is completely superimposable on one already constructed! 13. How many stereochemically different models are possible for 2,3-butanediol? 14. What characteristic does one of these...
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...
3. Cyclic compounds The presence of the ring in all but very large ring cyclic molecules prevents full rotation of the ring atoms. For this reason, stereoisomerism may also occur in cyclic molecules. a) Prepare a model of cyclohexane, C6H12. Draw the condensed formula. b) Build a model of methylcyclohexane (C7H14) by replacing one of the hydrogens of cyclohexane with a methyl group. Draw the skeletal formula for methylcyclohexane. 2 c) How many different isomers exist for methylcyclohexane (CyH34)? d)...
