WebThis chair conformation is the lowest energy conformation for cyclohexane and other six-membered rings. An alternate conformation for a six-membered ring is called the ‘boat ’: In the boat conformation, two of the substituents – those on the ‘bow’ and the ‘stern’ if you will – are brought close enough to each other to cause steric strain.
