NEET · Chemistry · STD 12 - p -Block elements - ll
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 & Solution
Correct Answer
(A) Both Statement \(I\) and Statement \(II\) are true.
Step-by-step Solution
Detailed explanation
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
