In benzene itself, each carbon atom is also bonded to a hydrogen atom; in derivatives of benzene**, one or more of the hydrogen atoms is replaced by other atoms or groups of atoms.*" Dictionary.com [Emily Lane](https://blog.ionscience.com/author/emily-lane) [0](https://blog.ionscience.com/understanding-the-benzene-ring#comments-listing) « Previous [1](https://blog.ionscience.com/topic/tac/page/1) Next » ## Subscribe to the ION newsletter Newsletter subscribers receive news and important information as soon as it is released ### Blog Categories -
