Morphology
The term is compositionally built: 'allyl' names the C3H5 radical and 'group' denotes a bonded assembly or substituent, so a learner who knows both constituents can derive 'an allyl radical substituent' from the parts. Although domain‑specific, this noun+noun chemistry construction is regular and cross‑linguistically common, making the phrase transparent.
Etymology
The noun allyl group may come from an old word for garlic, because early chemists found these kinds of chemical pieces in garlic and onions. The phrase gives a clear picture: allyl is a three-carbon 'reactive piece' that attaches to a larger molecule and group shows it is that attached part, so allyl group means that reactive bit on a molecule.
