• A. Bromic acid
• B. Hydrogen bromide acid
• C. Bromous acid
• D. Hydrobromic acid

Answer: (D)

Verified step by step guidance

1. Identify the acid type based on the formula HBr(aq). Since it is a binary acid composed of hydrogen and a halogen (bromine), it is classified as a binary acid.
2. Recall the naming convention for binary acids: when dissolved in water (aqueous solution), they are named with the prefix 'hydro-', followed by the root of the nonmetal element, and ending with the suffix '-ic acid'.
3. Apply this rule to HBr: the nonmetal is bromine, so the root is 'brom-'. Adding the prefix and suffix gives 'hydrobromic acid'.
4. Understand that names like 'bromic acid' or 'bromous acid' refer to oxyacids of bromine, which contain oxygen atoms, and thus do not apply to HBr.
5. Conclude that the correct name for HBr(aq) is 'hydrobromic acid' following the standard nomenclature for binary acids.
