Statement I : Acid strength increases in the order given as HF << HCl << HBr << HI.
Statement II : 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 acid strength increases.
In the light of the above statements, choose the correct answer from the options given below.
Statement II : 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 acid strength increases.
In the light of the above statements, choose the correct answer from the options given below.
- AStatement I is incorrect but Statement II is true.
- BBoth Statement I and Statement II are true.
- CBoth Statement I and Statement II are false.
- DStatement I is correct but Statement II is false.

Correct answer: B
In the modern periodic table, moving down the group as the size of halogen atom increases, the H - X bond length also increases as a result the bond enthalpy decreases. Hence, the acidic strength also increases.
So, the correct order of acidic strength is
HI > HBr > HCl > HF
