Morphology
The compound is fully compositional: 'ethyl' names a specific C2H5 substituent and 'group' denotes a bonded assembly, so 'ethyl group' straightforwardly means the ethyl substituent or assembly of atoms. This is a standard chemical noun–noun composition found across languages, so a B1 learner who already knows both constituents would understand the MWE.
Etymology
Ethyl group names a small part of a molecule: ethyl is a 'two-carbon piece' and group means several atoms joined together. When an ethyl group is joined to a molecule, it often changes how the whole molecule behaves, so the name points to the part that makes a compound different.
