A six-carbon ring that refuses to lie flat and flips between two comfy chairs instead.
means A colorless, flammable liquid hydrocarbon made of six CH2 units joined in a ring (C6H12), widely used as a solvent and as a feedstock for making nylon.
from Built from chemical word-parts rather than borrowed from any story: 'cyclo-' comes from the Greek 'kyklos' meaning circle or wheel, marking the closed ring of carbon atoms, while '-hexane' points to 'hexa-,' Greek for six, fused onto the '-ane' suffix chemists use for saturated hydrocarbons (compounds bonded as simply as possible, no double bonds). Put together, the name is really just a precise label — 'six-carbon ring, fully saturated' — coined in the 19th century as organic chemistry was busy inventing a systematic vocabulary for molecular shapes.
- shape
- chair conformation is lowest energy, not flat hexagon
- flip rate
- chairs interconvert thousands of times per second
- axial vs equatorial
- substituents swap positions every ring flip
- origin
- derived industrially from benzene via hydrogenation
