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.

• 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 1

Answer: (A)

Down the group acidic strength increases as bond length increases and bond strength decreases due to which ease of release of $H^{+}$ increases. Acidic strength increases
