Choose the correct answer from the options given below:

Taking stability as the factor, which one of the following represents correct relationship?

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.

Zr(Z = 40) and Hf(Z = 72) have similar atomic and ionic radii because of :

Given below are two statements:

Statement I:
The acidic strength of monosubstituted nitrophenol is higher than phenol because of electron withdrawing nitro group.

Statement II:
o-nitrophenol, m-nitrophenol and p-nitrophenol will have same acidic strength as they have one nitro group attached to the phenolic ring.
