Question

What is the name of $HBr$ (gas)?

Answer 1

Hint: In chemical nomenclature, the IUPAC Inorganic Chemical Nomenclature is a systematic method for naming inorganic compounds, recommended by the International Union of Pure and Applied Chemistry (IUPAC). Inorganic molecular compounds are named with prefixes. The most electronegative elements are written last with the suffix ide. So, in the solution, we will see how $HBr$ is named according to the IUPAC.

Complete Step By Step Answer:
We know that the compounds are named after IUPAC (International Union of Pure and Applied Chemistry). It is a systematic method for naming inorganic compounds. So, the given compound is $HBr$ (gas).
We must remember that inorganic molecular compounds are named with prefixes. The most electronegative elements are written last with the suffix ide. Therefore, in a given inorganic compound, bromine is more electronegative than hydrogen. The electronegativities of hydrogen and bromine are $2.2$ and $2.96$ respectively.
Therefore, based on the above rule, the name of the $HBr$ (gas) is Hydrogen Bromide.
 $HBr$ is an inorganic chemical compound and it can also be referred to as Hydrobromic acid because there is an electronegativity difference between hydrogen and bromide and it is a good acid. This is because bromide is a good leaving group.

Note:
Hydrobromic acid is mainly used to produce inorganic bromides, especially zinc bromide, calcium bromide and sodium bromide. It is a useful reagent for generating organic bromine compounds. Some ethers are cleaved with HBr. It also catalyzes the alkylation reaction and the extraction of certain minerals. Organic compounds of industrial importance prepared from hydrobromic acid include allyl bromide, tetrabromo bis(phenol) and bromoacetic acid.
