Question

Arrange hf hcl hbr hi in increasing acid characters

Answer 1

Acidic strength is defined as the ease of losing a proton, i.e H+. In the given compounds, HF has the strongest bond between the two ions. This is because of the small size of F-. At the same time, HI has the weakest bond between the ions. The reason being the large size of I-. Thus, we can write the order of acidic strength as :

HF < HCl < HBr < HI.
