I've seen this rule cited in several websites:

If the substituent contains no more than six carbon atoms, the compound's parent name is benzene

Could someone update me with the latest rule in naming alkylbenzenes (or phenylalkanes) when the alkyl chain (side chain) does not have any functional groups. Would appreciate if you could provide citations for the rule. Thank you.

For me this has always been a rule:

aromatic rings will always be treated as a parent chain as long as there are no substituents with functional groups in them

But I am not able to find a source to stand up for it. :/
