The correct name for P4O10 is tetraphosphorus decoxide. This can be determined by analyzing the composition of the compound.
P4O10 consists of four phosphorus (P) atoms and ten oxygen (O) atoms. In chemical nomenclature, prefixes are used to indicate the number of atoms present. The prefix ‘tetra-‘ indicates four, and ‘deca-‘ indicates ten. Therefore, when we combine these prefixes with the names of the elements, we arrive at ‘tetraphosphorus decoxide’.
To clarify, the other options provided are incorrect for the following reasons:
- Phosphorus IV oxide would imply a different oxidation state and a different formula.
- Phosphorus oxide is too vague and does not specify the number of phosphorus and oxygen atoms.
- Diphosphorus pentoxide does not match the formula since there are four phosphorus atoms in P4O10.
- Phosphorus II oxide also incorrectly suggests a different oxidation state.
Thus, tetraphosphorus decoxide is the accurate and accepted name for P4O10.
