Step-by-step explanation:
A binary compound is a compound which is formed by combination of two atoms.
For Example:
is a binary covalent compound because sharing of electrons takes place between two atoms nitrogen and oxygen.
The nomenclature of covalent compound is given by:
1. The less electronegative element is written first.
2. The more electronegative element is written then, and a suffix is added with it. The suffix added is '-ide'.
3. If atoms of an element is greater than 1, then prefixes are added which are 'mono' for 1 atom, 'di' for 2 atoms, 'tri' for 3 atoms and so on..
So, the IUPAC name for
is nitrogen monooxide.
