- Which do you expect to be the more stable conformation of cis-1,3-dimethylcyclobutane, A or B? Why?Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. a. Do enantiomers have the same molecular formula? b. Does one structural formula represent both members of a pair of enantiomers? c. Are enantiomers stereoisomers?Can someone tell me what the appropiate E/Z conformation for this example is?
- Part D. Do the two structures A and B of each pair drawn below represent the same molecule, constitutional isomers, or stereoisomers? If A and B are stereoisomers, further classify them as enantiomers or diastereomers.How are each pair of compounds related (enantiomers, diastereomers, meso, same, constitutional isomers)? Relate A-B, B-D, B-C, and C-D. Label each as chiral or achiral. Which are optically active?For the 1,2-dichlorocyclohexane stereoisomers, which conformation of the trans stereoisomer has the lower energy, the diaxial or the diequatorial conformer? Which isomer and conformation of the three you built has the lowest energy? E of all the isomers of 1,2-dichlorocyclohexane. Explain the differences in energy, i.e., identify the sources of strain in the conformations you built. Show the sources of strain in a drawing.
- Add wedges and dashed wedges for all stereogenic centers with the following information: the configuration at C10 is R, the configuration at C13 is S, and all substituents at ring fusions are trans to each other.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?provide chari conformations and chair flip, which one is most stable and why?
- Draw Newman Projections representing the two highest and two lowest energy conformers of (3S,4S)-4-tert-butyl-2,3-dimethyloctane as viewed along the C3-C4 bond. b.) Label each conformer with theappropriate description then analyze them and rank their energies and explain your reasoning by specifyingthe types of interactions. (Hint: Draw the first and then rotate only the front or back carbon)What are all the possible chair representations with energy ranking from lowest to highest for the following cyclohexane stereoisomers?Which chair conformation is more stable? Is it the right because bromine has a larger mass than a methyl group? Or is it the left because the methyl group has three hydrogens stemming from the carbon and is therefore ‘bulkier?’
