The molecule in three dimensions

Rotate and inspect the atoms. Loaded only when you ask, so the page stays light.

The drawing above is a diagram of what is bonded to what. A molecule is not flat, and the model here is one low-energy shape generated from the connectivity — useful for seeing which groups can reach each other, and not a measured structure. A real sample is a population of conformations, interconverting.

Other names for it

The systematic name on this record is iodobenzene.

The sources also call it Phenyl iodide, Benzene, iodo-, Benzene iodide, Iodinebenzol, Iodo-benzene, 9HK5L7YBBR, 4-iodobenzene.
