Given the planar trisubstituted cyclohexane below, fill in all boxes (with H, F,Cl or Br) to complete the two possible cyclohexane chair conformations.
Which is the more stable conformer?
Chair1
Chair2
Given the planar trisubstituted cyclohexane below, fill in all boxes (with H or Cl) to complete the two possible cyclohexane chair conformations.
A trisubstituted cyclohexane compound is given below in its chair conformation. Draw the corresponding planar (overhead) representation, using wedges and hashed bonds to indicate the substituent positions. To be graded properly, include the hydrogen atoms on the chirality centers (asymmetric carbons). Be sure that both wedges/hashed bonds are drawn on the outside of the ring, or else the stereochemistry may be interpreted as square planar.
Given cyclohexane in a chair conformation, substitute two of the H labels with Br to construct the most stable isomer and conformation of 1,3-dibromocyclohexane.
with explanation
1) Draw a chair conformation of cyclohexane. Then, draw and level properly all axial and equatorial positions on chair form of cyclohexane. 2) Draw chair, half-chair and boat conformations of ethyl cyclohexane and draw an energy diagram to explain their relative stability: 3) Draw two possible chair conformations for each of the mono-substituted cyclohexanes and determine their relative stability with proper explanation. OH 4) Draw two possible chair conformations for each of the di-substituted cyclohexanes and determine their...
Determine the total number of conformers for the
tetra-substituted cyclohexane structure (i.e., ethyl-methyl), A
given below.
Determine the total number of conformers for the tetra-substituted cyelohexane structure (i.e., ethyl-methyl), A given below. Draw the chair structure for the third most stable conformer of A, the conformer that is six level of instability from the most unstable and the conformer that is eight level of stability from the most stable conformer. draw only the required structures for the eonformers of A...
Two isomers (A and B) of trisubstituted Cyclohexane are shown below. Are these two isomers of equal energy? If so, why? Or is one more energetic than the other? If so, why? And which one? Explain in sufficient detail. To entirely illustrate your point, use drawings in addition to the ones provided.
6. Build the cyclobutane ring and study the angle strain and torsional strain. Draw the structures to explain these factors. 7. The conformation of cyclobutane is slightly folded. Folding gives partial relief from the eclipsing of bonds, as shown in the Newman projection. Compare this actual structure with the hypothetical planar structure. Draw the relevant structures. 8. trans-1,2-Dimethylcyclobutane is more stable than cis-1,2-dimethylcyclobutane, but cis-1,3- dimethylcyclobutane is more stable than trans-1,3-dimethylcyclobutane. Use the molecular models to find the reasons for...
