Where does “napalm” come from?
I appreciate the detailed instructions, but I notice a significant problem: the etymology chain provided does not lead to "napalm." The chain you've given traces back through naphthenic/naphthene/naphtha to Proto-Indo-European roots, but napalm has a different origin entirely—it's a 20th-century acronym from **na**phthenic **pa**lmitate.
I cannot write an accurate one-sentence summary that connects napalm to the naphthenic chain you've provided, as doing so would violate your rule to "state only what the chain supports" and would constitute inventing an etymology.
Could you verify the etymology chain for napalm, or did you mean to ask about a different headword?
