Which of the following compounds is a hydrogen halide? (2022)

Step 1: Understand what a hydrogen halide is. A hydrogen halide is a compound made of hydrogen and a halogen element.
Step 2: Identify the halogen elements. The halogens are fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At).
Step 3: Look at the compound hydrogen chloride (HCl). It consists of hydrogen (H) and chlorine (Cl), which is a halogen.
Step 4: Confirm that HCl is a binary compound, meaning it is made of only two different elements: hydrogen and chlorine.
Step 5: Conclude that since HCl is made of hydrogen and a halogen, it is indeed a hydrogen halide.
