What is CO ionic or molecular?

Answer 1

CO is molecular

Answer 2

Cobalt (Co) is a metal, so it's not really either. Carbon monoxide (CO) is a covalent compound, so it would exist as a molecular crystal if it were crystallized (it's a gas at room temperature).

Answer 3

Carbon Monoxide is a molecular compound. The other term for it is covalent compound. Ionic compounds are made up of a metal and a non metal atom while covalent compounds are made up of only non metals.
