Morphology

dichloromethane = chloromethane (semi-transparent) = di + chloro + methane

Adding the numeric prefix 'di-' to 'chloromethane' straightforwardly signals two chlorine substituents, a clear morphological operation in chemical nomenclature.

Etymology

Dichloromethane breaks into parts: di- meaning 'two', chloro- meaning 'chlorine', and methane meaning 'a simple carbon gas'. So the name literally says 'methane' with two 'chlorine' atoms attached, which helps you remember its chemical make-up and why it is a small, volatile solvent that evaporates quickly.
