Question

Which is the name for SO3? silver oxide trisulfur oxide sulfur trioxide silver trioxide

Answer 1

Answer : The correct name of the compound is, sulfur trioxide.

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 named first.
• The more electronegative element is named second and then 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..

`SO_3` is a covalent compound because sharing of electrons takes place between sulfur and oxygen. Both the elements are non-metals and hence, will form covalent bond.

So, the name for
`SO_3` is sulfur trioxide.

Answer 2

Answer: sulfur trioxide

Explanation:
`SO_3` is a covalent compound because sharing of electrons takes place between sulphur and oxygen. 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 and so on..

So, the IUPAC name for
`SO_3` is sulphur trioxide.
