Cis vs Trans Conformations - Online Tutor, Practice Problems & Exam Prep

Give the planar form of the chair conformation below as if you are looking down on it from above.

Refer to the representations below to complete the table. Fill out the table with the required positions (axial = a; equatorial = e) of the two groups for a conformation to be cis or trans. For example, two groups that must be both equatorial should be denoted as (e,e).

Consider the following chair conformation:

Illustrate the planar form of the chair conformation based on its top view. 

Name the following compounds using cis-trans nomenclature.

Provide the planar form of the chair conformation below as if you are observing it from above.

Write the names of the following compounds. Note that when the two bonds to methyls are up (or down), they are cis. When one bond to methyl is up while another bond to methyl is down, the bonds are trans.

Determine whether each of the following isomers is cis or trans.

Indicate if the structures below are cis or trans isomers.

(i)

(ii)

(iii)

Determine which structure(s) correspond to a cis isomer.

Consider the chair shown below. Draw the same molecule with its axial and equatorial bonds except that the headrest is on the left side and the footrest is on the right side.

Sketch the chair conformations for the compound shown below. Label the structures as cis or trans.

Provide the name of the cycloalkanes shown below using cis-trans nomenclature:
