Editing Cyclohexane conformation (section)

== Coplanar carbons ==
Another way to compare the stability within two molecules of cyclohexane in the same conformation is to evaluate the number of coplanar carbons in each molecule.<ref name="Nelson2011" /> Coplanar carbons are carbons that are all on the same plane. Increasing the number of coplanar carbons increases the number of [[Eclipsed conformation|eclipsing]] substituents trying to form a 120°, which is unattainable due to the overlapping hydrogens.<ref>{{Cite web |title=Conformations of Cyclohexane {{!}} Chair, Boat & Twist-Boat Conformation - Video & Lesson Transcript |url=https://study.com/learn/lesson/conformations-cyclohexane-chair-boat-twist-boat.html |access-date=2022-11-18 |website=study.com |language=en}}</ref> This overlap increases the overall torsional strain and decreases the stability of the conformation. Cyclohexane diminishes the torsional strain from eclipsing substituents through adopting a conformation with fewer coplanar carbons.<ref>{{Cite web |date=2021-12-15 |title=4.3: Conformation Analysis of Cyclohexane |url=https://chem.libretexts.org/Bookshelves/Organic_Chemistry/Organic_Chemistry_I_(Liu)/04%3A_Conformations_of_Alkanes_and_Cycloalkanes/4.03%3A_Conformation_Analysis_of_Cyclohexane |access-date=2022-11-18 |website=Chemistry LibreTexts |language=en}}</ref> For example, if a half-chair conformation contains four coplanar carbons and another half-chair conformation contains five coplanar carbons, the conformation with four coplanar carbons will be more stable.<ref name="Nelson2011" />
