Answer: The correct answer is carbon monoxide.
Explanation:
CO is a covalent compound because in this compound sharing of electrons is taking place carbon and oxygen. As, both the elements are non-metals here, so they will form covalent bond.
The nomenclature of covalent compound is given by some following rules:
- The less electronegative element is written first.
- The more electronegative element is written then, and a suffix is added with it. The suffix added is '-ide'.
- If atoms of an elements present are more than 1, so prefixes are added to it such as 'mono' for 1 atom, 'di' for 2 atoms, 'tri' for 3 atoms and so on..
Thus, the IUPAC name for CO comes out to be carbon monoxide.
