We would see a cyclic molecule such as cyclohexane A as a flat ring with the hydrogen atoms around it.
His work on the structure of the metal carbonyls had suggested that a cyclic structure was improbable. 他对金属羰基结构的研究表明，环状结构是不可能的。

- A traditional jet fuel has more straight- and branched-chain hydrocarbon molecules called alkanes, whereas the new fuel has more cyclic molecules that look like pairs of rings.
- The reaction produces a cyclic sulfonium compound.
