When are compounds named in terms of benzene vs in terms of phenyl? I dont understand why C6H5Cl is named in terms of benzene while C6H5OH is named in terms of phenyl.

The C6H5- group is called ‘phenyl'. C6H5OH cannot be called phenyl alcohol because it does not contain the alcohol group -CH2OH. Therefore it is called phenol. C6H5Cl is called chlorobenzene because it is the chloro-derivative of benzene. It can also be called phenyl chloride, because it consists of a phenyl group and a chloride group, and it can be made from a chloride salt, phenol and sulphuric acid. But chlorobenzene is a better name because it is consistent with other derivatives such as nitrobenzene and benzensulphonic acid.

Organic chemical names come from many sources. Some, like the increasingly long alkanes become regular at pentane or pentyl followed by hexyl, nonyl, etc., etc.
BUT a lot of organic chemical names are just what people decided a Loooong time ago. Like methyl, ethyl, propyl, butyl.
and C5H5OH isn’t exactly named “phenyl” but rather phenol which is, I suspect, one of the many, quaint original names. However, I don’t know, it may relate to “phenyl”.
a snippet from wikipedia: In 1836, Auguste Laurent coined the name "phène" for benzene; this is the root of the word "phenol" and "phenyl". In 1843, French chemist Charles Gerhardt coined the name "phénol".
