Acidic strength increase in the order given as…..

HF << HCl << HBr << HI.

What is wrong about this statement?

Ans~
there is nothing wrong about this statement.

1. In the modern periodic table.moving down the group as the size of halogen atom increases, the H-X bond length also increase as a result the bond enthalpy decreases. Hence.the acidic strength also increases .

2. As the size of the elements F,Cl,Br,I increases down the group, the bond strength of HF, HCl, HBr, and HI decreases and so the acidic strength increases.
