What is the prefix for oxygen in [tex]As_2 O_5[/tex]?

A. tri-
B. di-
C. mono-
D. penta-


Sagot :

To determine the appropriate prefix for oxygen in the chemical compound \( \text{As}_2\text{O}_5 \), we need to consider the number of oxygen atoms present in the formula. Here is the step-by-step process:

1. Identify the Number of Oxygen Atoms: The chemical formula \( \text{As}_2\text{O}_5 \) indicates that there are 5 oxygen atoms present in the compound.

2. Determine the Corresponding Prefix: The prefixes used in chemical nomenclature are based on the number of atoms. Here is a list of numerical prefixes for the numbers 1 through 5:
- 1 atom: mono-
- 2 atoms: di-
- 3 atoms: tri-
- 4 atoms: tetra-
- 5 atoms: penta-

3. Select the Correct Prefix for 5 Atoms: Since there are 5 oxygen atoms in \( \text{As}_2\text{O}_5 \), the correct prefix for 5 is "penta-".

Therefore, the prefix for oxygen in [tex]\( \text{As}_2\text{O}_5 \)[/tex] is penta-.
