    $\begingroup$ It is phenyl all right. Then again, there is a broader term: aryl. $\endgroup$ – Ivan Neretin Mar 21 '18 at 11:39
  • $\begingroup$ What is the difference between aryl and arylene? She said it was close to arylene but that arylene was a more general name $\endgroup$ – kichi Mar 21 '18 at 11:45
  • $\begingroup$ 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) $\endgroup$ – kichi Mar 21 '18 at 11:45
  • $\begingroup$ It had to be where the hydrogen atom is removed not substituted $\endgroup$ – 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.
