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
