Answer : The correct name of [tex]H_2S[/tex] compound is, Hydrogen sulfide.
Explanation :
As we know that, [tex]H_2S[/tex] is a covalent compound in which the sharing of electrons takes place between hydrogen and sulfur. Both the elements are non-metals and hence, will form covalent bond.
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..
In [tex]H_2S[/tex], hydrogen is an electropositive element and sulfur is an electronegative element.
So, the correct name for [tex]H_2S[/tex] is hydrogen sulfide.
