Cyclohexane Chair Conformations Practice Quiz

August 10, 2022 By Leah4sci 76 Comments

Chair Conformations Practice Quiz Leah4sciChair conformations can present quite the challenge in Organic Chemistry.

But they don't have to.

Start by gaining your foundation in the Chair Conformations Tutorial Series. 

Then test your knowledge and understanding of this topic with the quiz below.

Scroll to the very bottom of this quiz for a link to the FREE quiz solutions PDF to ensure you've got this down. Coming Soon!

Part 1: Warmup Questions

Question 1: Name, then Draw BOTH chair conformations for each of the following cyclohexane hexagon molecules.

Hint: Need help? Review the Drawing Chairs tutorial

Name and draw chair conformation practice quiz leah4sci

 

Question 2: Determine the total number of Axial and Equatorial hydrogen atoms in trans-decalin as shown below:

trans-decalin-chair-conformation-practice

Question 3: Convert the following chair conformations into planar ‘hexagon' structures:

chair-conformation-to-cyclohexane-hexagon-practice

 

Part 2: Cyclohexane Ring Flips and Chair Stability

Question 4: Draw the ring flip for each of the following chair conformations

Hint: Don't forget, up stays up and down stays down. As taught in this Tutorial Video.

Question 5: Draw the lowest energy chair conformation for each of the following cyclohexane structures.

Beginner students: Draw BOTH chairs and compare energy and stability.

Advanced students: See if you can visualize the molecule and draw ONLY the more stable structure.

chair-conformation-axial-and-equatorial-lowest-energy-practice-questions

Question 6: Determine if the Cis or Trans chair conformation is more stable for each of the following molecules. (Read for a quick review of cis/trans)

a) 1,2-dibromocyclohexane

b) 1,3-diethylcyclohexanol

c) 4-methylcyclohexanamine

Part 3: Advanced

Question 7: Draw ALL possible chair conformations for 2-tert-butylcyclohexanol then rank in order of most to least stable.

Question 8: Answer this question WITHOUT drawing a chair conformation/ring flip. Determine if the highlighted atom will appear in the axial or equatorial position in the more stable chair conformation.

Challenge Question: 

Convert the following

a) Newman Projection into a chair conformation

b) Chair conformation into a Newman ProjectionChallenge Convert the following newman projection into a chair conformation and chair conformation into a newman projection in Practice Quiz

Need to Review? Study the Chair Conformations Tutorial Series.

    I watched the tutorial but I am able to classify the chair conformations in question 3 and 4 in order of stability. Can you provide me with a rule so that when I see structures like these I can easily recognize which one is more stable. By the way since I have been watching your videos I stopped relying on google to get answers for my homework. I was able to solve them myself. Your explanation is so clear and enjoyable

    Thank you

As I was trying to do a final review on chair conformations for my test tomorrow, I find that I don’t have the answers to compare to. The solutions may come too late in my case…Either way, thank you so very much for making Organic Chemistry easier to understand. I wish you were my college professor!
