Explanation:

Part A

To name \( \text{AlBr}_3 \), we use ionic compound naming rules. Aluminum (\( \text{Al} \)) is a metal with a fixed charge (\( +3 \) in this case, but for main - group metals with fixed charges, we don't need to use Roman numerals in the common name). Bromine (\( \text{Br} \)) forms the bromide ion (\( \text{Br}^- \)). The ratio of \( \text{Al}^{3 + } \) to \( \text{Br}^- \) is \( 1:3 \), but in the common name of ionic compounds with metals having fixed charges, we simply use the metal name followed by the non - metal name with the suffix - ide. So we name it aluminum bromide. "Monoaluminum tribromide" is incorrect as we don't use "mono - " for the metal in ionic compound naming. "Aluminum(III) bromide" is the systematic name, but the common name is just aluminum bromide. "Aluminum tribromide" is also incorrect as we don't use prefixes for ionic compounds with metals of fixed charge.

The compound \( \text{HC}_2\text{H}_3\text{O}_2(\text{aq}) \) is acetic acid. The formula \( \text{HC}_2\text{H}_3\text{O}_2 \) represents the acetic acid molecule (ethanoic acid in IUPAC nomenclature, but the common name is acetic acid). "Hydroacetous acid", "hydroacetic acid", and "acetous acid" are incorrect names for this compound.

Answer:

B. aluminum bromide
