Solution Steps

Step 1: Naming Binary Covalent Compounds

Binary covalent compounds are named using prefixes to indicate the number of atoms of each element. The first element keeps its name, and the second element's name is modified to end in "-ide."

Step 2: Naming Binary Acids

Binary acids are named using the prefix "hydro-" followed by the root of the nonmetal element and the suffix "-ic," followed by the word "acid."

Step 3: Applying the Rules to Each Compound

a. $\mathrm{PF}_{3}$: Phosphorus trifluoride

  • "Phosphorus" is the name of the first element.
  • "Tri-" indicates three fluorine atoms.
  • "Fluoride" is the modified name of fluorine.

b. $\mathrm{H}_{2} \mathrm{Se}(\mathrm{aq})$: Hydroselenic acid

  • "Hydro-" prefix.
  • "Selen-" root from selenium.
  • "-ic" suffix.
  • "Acid" at the end.

c. $\mathrm{OCl}_{2}$: Oxygen dichloride

  • "Oxygen" is the name of the first element.
  • "Di-" indicates two chlorine atoms.
  • "Chloride" is the modified name of chlorine.

Final Answer

\[ \begin{aligned} &\text{a. } \mathrm{PF}_{3} \quad \text{Phosphorus trifluoride} \\ &\text{b. } \mathrm{H}_{2} \mathrm{Se}(\mathrm{aq}) \quad \text{Hydroselenic acid} \\ &\text{c. } \mathrm{OCl}_{2} \quad \text{Oxygen dichloride} \\ \end{aligned} \]

\[ \boxed{ \begin{aligned} &\text{a. Phosphorus trifluoride} \\ &\text{b. Hydroselenic acid} \\ &\text{c. Oxygen dichloride} \\ \end{aligned} } \]
