Morphology
The meaning is a straightforward composition of 'long' (denoting extended length) and 'chain' (a linked sequence, here of atoms), so a learner who knows both words can infer a sequence of atoms that is lengthy. This is a literal, domain-specific use following ordinary English modifier + noun patterns and is cross-linguistically transparent, so it should be clear to a B1 learner.
Etymology
The noun long chain comes from the image of a real chain made of many links in a long line. In chemistry, each link is like an atom, so a long chain means 'many atoms joined together' in one molecule.
