For the compound below draw all of its stereoisomers, be sure to label the enantiomeric pairs and any meso compounds
In the previous problem, you saw that there were two chiral carbons in 4-bromo-3-hydroxypentanal. That molecule is drawn below with the chiral carbons circled. What is the maximum number of stereoisomers that can exist for this molecule? Can you help me, please? Can you explain to me?
If you think you know your definitions, try this difficult problem. In the mesostructures, show how C3 is not asymmetric, nor is it a chiral center, yet it is a stereocenter.
On b), I understand that we don't know which side of the molecule the Cl would attach on, but I was under the impression that we only show stereochemistry on a chiral center, and I do not see where the chiral center is on this molecule. Would you be able to explain this?
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.
I don't understand why the first one and second one are cis and trans respectively. Wouldn't the first one be trans-1,2-dimethylcyclobutane because the torsional strain wouldn't allow the carbons to be in the same conformation. Meaning one of the carbons would be up and then the next would be down and so on. Since both methyl groups are equatorial and the first and second carbons are arranged up and down, wouldn't it be trans. Same logic for the second molecule. Carbon 1, which is attached to the methyl is down, carbon 3 which is attached to the methyl should be down also because of torsional strain, and since both methyl are in axial (or equatorial?), it would be cis. Or is it based off of the way the carbons are positioned in the picture?
Please answer this NEATLY, COMPLETELY, and CORRECTLY for an UPVOTE. Long and detailed explanations are not needed. Keep it short, brief, and direct because I only need the answers. Which conformation is the most stable representation of 2,3-dimethylbutane?
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. Long and detailed explanations are not needed. Keep it short, brief, and direct because I only need the answers as soon as possible. Calculate the total strain energy in each of the two chair conformations of cis-1-tert-butyl-4-chlorocyclohexane. By how much energy is the more stable conformation favored (this is the difference in energy between the two conformations)? NOTE: The strain energy for one H,Cl interaction is 1.0 kJ/mol while for H,-C(CH3)3 (t-butyl) is 11.4 kJ/mol.
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)
Draw the most stable conformation of the molecule while taking into account the approximate values of the energies of the following skew interactions:
