Chair 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
Question 2: Determine the total number of Axial and Equatorial hydrogen atoms in trans-decalin as shown below:
Question 3: Convert the following chair conformations into planar ‘hexagon' structures:
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.
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 Projection

First, thank you for this tutorial, appreciate your work here, you make it so simple and easy, also, Do you have the pdf solution, I couldn’t find it
hello! would there be answers to the quiz soon?
When will the answers be posted?
Ma’am Can you please make a detailed video on optical isomerism
You are teaching very well
Where are the solutions?
can you please put the solutions. I just finished taking the quiz, but all that effort is kind of useless without solutions. thank you for all your hard work on this website 🙂
How may I get the answers to this practice quiz? Thank you.
how can i download the quiz
Is the answer key available?
Are you going to post the answers?
When will you be posting the solutions to these? I need help with 3d
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
where can we find the answers?
where are the answers please?
can you send me link of this quiz please
I can’t find it
hello, is the PDF solutions complete yet? I would love to check to see if I am correct in my thinking. Thank you

I can’t find the pdf with answers to this quiz
Has the solutions been posted? Can’t seem to find them.
I really appreciate your tutorials so much. Everything gets explained so easily… thank you so much. One small request for the future. Would you mind posting the solutions along with the quiz? 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!
Hi Leah,
Those are very helpful videos. Have you uploaded the quiz solution yet though?
Thanks!
When will the solution be added?
I am very confused when it comes to chair conformation’s.
Sharon: Start with the tutorials before attempting the quiz and let me know if that helps
