Answer : The correct name for [tex]PH_3[/tex] is, phosphorous trihydride.
Explanation :
Covalent compound : It is defined as the compound which is formed by the sharing of electrons between the atoms forming a compound.
The covalent compound are usually formed when two non-metals react.
The nomenclature of covalent compound is given by:
- 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 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..
[tex]PH_3[/tex] is a covalent compound because sharing of electrons takes place between phosphorous and hydrogen atom. Both the elements are non-metals and hence, will form covalent bond.
So, the correct name for [tex]PH_3[/tex] is, phosphorous trihydride.
