Answer: B) [tex]P_4I_{10}[/tex]
Explanation: [tex]P_4I_{10}[/tex] is a covalent compound because sharing of electrons takes place between phosphorous and iodine. Both the elements are non-metals and hence, will form covalent bond.
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 , 'tetra' for 4 atoms and so on.
So, the IUPAC name for [tex]P_4I_{10}[/tex] is tetraphosphorus decaiodide.
