Question

what is the name of this binary molecular compound? co carbon oxide calcium monoxide monocarbon monoxide carbon monoxide

Explanation:

Binary molecular compounds are named using prefixes to indicate the number of each type of atom. The formula \(CO\) has one carbon (\(C\)) atom and one oxygen (\(O\)) atom. The prefix for one is "mono -", but for the first element (carbon here), the "mono -" prefix is often omitted. So it's named carbon monoxide. "Carbon oxide" is too general as it doesn't specify the number of oxygen atoms. "Calcium monoxide" is incorrect as the symbol \(Ca\) represents calcium, not \(C\) (carbon). "Monocarbon monoxide" would be redundant as the first "mono -" is typically not used for the first element in such naming.

Answer:

carbon monoxide
