Question

(03.04 MC) What is the correct name for PH3? (3 points) Monophosphorus trihydride Monophosphorus hydroxide Phosphorus hydride Phosphorus trihydride

Answer 1

Answer: The name for $PH_3$ is phosphorus trihydride.

Explanation:

Covalent compound is defined as the compound which is formed by the sharing of electrons between the atoms forming a compound. These are usually formed when two non-metals react.

$PH_3$ is a covalent compound because sharing of electrons takes place between hydrogen and phosphorus. 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..

Hence, the name for $PH_3$ is phosphorus trihydride.
