Bonus
The lack of destabilizing flagpole interactions in this conformation makes it more stable than the boat conformation. For 10 points each:
[10h] Name this conformation. Axial groups are converted to equatorial groups during a “flipping” which interconverts between two forms of this conformation.
ANSWER: chair conformation [accept chair flipping]
[10m] This alkane is more stable in its chair conformation than its boat conformation. This cyclic molecule is produced industrially from the complete hydrogenation of benzene.
ANSWER: cyclohexane [prompt on C6H12; reject “cyclohexene”]
[10e] Cyclohexane’s chair and boat forms exemplify the “conformational” type of these molecules. The “structural” form of these molecules have the same atoms but different chemical structures.
ANSWER: isomers [accept structural isomers or conformational isomers; accept word forms like isomerism]
