Question

Arrange the acids in order of increasing acidic
strength; HI, HBr,HCl, HF. Give reason for your
answer.​

Answer 1

Answer:

HF less than HCl less than HBr less than HI

Explanation:

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- , this, we can write the order of acidic strength as:

HF less than HCl less than HBr less than HI
