Correct option:
The correct name for is diphosphorus pentoxide.
Why is called diphosphorus pentoxide?
is commonly known as diphosphorus pentoxide.
Phosphorus pentoxide has an intriguing property in that is actually its empirical formula, whereas
is its actual molecular formula.
However, the name of the chemical was obtained from its empirical formula rather than from its molecular formula. The official name for this substance is diphosphorus pentoxide.
Oxygen-containing binary compounds have "oxide" as their "last name." Phosphorus is the "first name."
We list each atom's numbers below:
The di- and Penta- prefixes are used to indicate the presence of two and five oxygen atoms, respectively, in the molecule.
