quick orgo question (from 2012 destroyer #75)

[kies89]

it is naming a compound and i narrowed it down with

phenyl-2-methylbutanoate
or
phenoxy-2-methylbutanoate

the benzene ring is attached to ester, (-O-BENZENE)
so i thought it is phenoxy, but the answer choice says phenyl

if phenyl, shoulnd R should be directly attached to benzene?
and if phenoxy, O is attached to benzene?

since ester group's O is attached to benzene,
i thought it was phenoxy but the answer is phenyl

can anyone help plz?

Phenoxy would be for the ether, phenyl is for esters.

When naming esters the group on on the oxygen is 1st in the whole name and it is specifically "phenyl" since the benzene is a substituent / it's smaller than the molecule it is attached to.
