Statement I: Acid strength increases in the order given as HF

Question

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.

Acidic strength of hydracids increases in order

$HF ≪ HCl ≪ HBr ≪ HI$

So, statement-I is true
The above order of acidic strength is due to decrease in bond strength. As the size of atom increases, bond length increases and bond strength decreases.
Thus, statement I and statement II are true
