Morphology

ethylene + tetrachloride

The compound name is directly compositional: 'ethylene' (the hydrocarbon) combined with 'tetrachloride' (having four chlorine atoms) yields the tetrachloride derivative of ethylene, i.e. an ethylene molecule with four chlorines, which aligns with standard chemical naming patterns. Although technical, this morphological and morphological-semantic mapping is predictable and cross-linguistically regular, so a learner who knows both constituents can infer the meaning.

Etymology

Ethylene tetrachloride describes the chemical: ethylene is the two-carbon part and tetrachloride means 'four chlorine atoms' attached. Think of ethylene with four little chlorine 'flags' on it — that picture helps you remember it is a chlorinated chemical that was once 'used to treat hookworm' but later stopped because it was dangerous.
