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 $Hl$ decreases and the acid strength increases.
In the light of the above statements, choose the correct answer from the options given below.

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

Answer 1

The correct option is C Both Statement I and Statement II are true

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.
Both the statements are correct.
