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.

MCQ

Statement $I :$ Acid strength increases in the order given as $\mathrm{HF}<\mathrm{HCl}<<\mathrm{HBr}<<\mathrm{HI}$

Statement $II :$ As the size of the elements $\mathrm{F}, \mathrm{Cl}, \mathrm{Br}, \mathrm{I}$ increases down the group, the bond strength of $\mathrm{HF}$, 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.

A
Both Statement $I$ and Statement $II$ are true.
B
Both Statement $I$ and Statement $II$ are false.
C
Statement $I$ is correct but Statement $II$ is false.
D
Statement $I$ is incorrect but Statement $II$ is true.

Answer

In hydra acids acidic strength increases an moving down the group as acid easily release $\mathrm{H}^{+}$ and conjugate anion stabilise due to decrease in charge density
