Morphology

carbon + monoxide

The compound is compositional: 'monoxide' denotes an oxide with one oxygen atom and 'carbon' names the element, so a learner who knows both constituents can infer it is the oxide of carbon (a carbon + one-oxygen compound, typically a gas). While specific properties like being colorless, odorless, and highly poisonous are extra lexical knowledge, the basic referent is directly derivable from the parts.

Etymology

Carbon monoxide gets its name from two parts: carbon (the material in coal and wood) and monoxide, which literally means 'one oxygen'. It was named this way because when carbon burns without enough air it makes a gas with only one oxygen, and that gas is colorless, has no smell, and is very poisonous, so the name now refers to this dangerous gas.
