Morphology

benzoyl + group

The compound is a straightforward noun–noun combination: 'benzoyl' names a specific radical derived from benzoic acid and 'group' denotes a bonded assembly of atoms, so the phrase simply refers to that benzoyl radical acting as a substituent. Although technical, the meaning is compositionally predictable and follows normal chemical naming patterns (and equivalents exist in other languages), so a learner who knows both constituents will readily infer the MWE meaning.

Etymology

The noun benzoyl group comes from benzoic acid, which was named for benzoin, a sticky tree resin old chemists studied. The ending -oyl means 'a small part taken from an acid', so the name shows this is the C6H5CO- piece of a molecule.
