# What is a benzene ring minus a hydrogen atom called?

I thought it was Phenyl but the teacher said it wasnt and that it started with "A" I cant seem to figure it out

• It is phenyl all right. Then again, there is a broader term: aryl. – Ivan Neretin Mar 21 '18 at 11:39
• What is the difference between aryl and arylene? She said it was close to arylene but that arylene was a more general name – kichi Mar 21 '18 at 11:45
• Is it that the latter had a hydrogen atom removed from two benzene rings? If so, is there any other case where a benzene ring or more have one h atom removed for each(i could only find the other name for arylene that is arenediyl) – kichi Mar 21 '18 at 11:45
• It had to be where the hydrogen atom is removed not substituted – kichi Mar 21 '18 at 11:47

You could be referring to "aryl". "Phenyl" is specific to $\ce{C_6H_5}$, "aryl" is generic to monovalent benzenoid aromatic ring groups.
