CHCH(OH)-CH(OH)-CH3 PART 3: 23-BUTANEDIOL Build as many models of 2.3-butanediol as you can. First, attach two...
19-26 thanks! 19-29* 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...
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. PART 4:2,3-DICHLOROPENTANE CH, CH(C)-CHC)-CH2CH Build a model...
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...
3. Diastereomers and Meso Forms. When a molecule has two or more stereogenic centers, stereoisomers that are not mirror images can exist; these are called diastereoisomers. Within this general class, there are special types of stereoisomers that are always optically inactive and are called meso forms. Construct a model with four different colored balls about a carbon center. Construct another identical to the first and verify this by the superimposition test. Now remove the same colored balls, blue (C from...
Week 10- Constitutional isomers Constitutional isomers have the same molecular formula, but their atoms are bonded in different orders. These may be further distinguished as chain isomers, which differ only in hydrocarbon chain structure, positional isomers, which differ in the location of a functional group, and functional group isomers which differ in the nature of their functional groups. Typically chain and position isomers show only modest differences in their physical and chemical properties, while functional group isomers differ greatly from...
please answer what ever you can 3. Name 2 important cations, and state their functions in humans. 4. How many mEq are in 2L of 0.5M NaCl ? 5. How many ml of 2M NaOH would it take to neutralize 20ml of 0.5M HCI ? 6. Draw the structural formula for 3-methyl-1-butanal. 7. Name the following molecule: CH3 - CH2 - CH2 - CH2 - CH2 - CH-OH 8. For the molecular composition, C6H120 draw 2 different isomers. 9. Name...
