Which of the following statement is not true?

Question

Which of the following statement is not true? (A) HOCl is a stronger acid than HOBr (B) HF is a stronger acid than HCl (C) Among halide ions, iodide is the most powerful reducing agent (D) Fluorine is the only halogen that does not show a variable oxidation state

Tardigrade Admin · Accepted Answer

Due to strong H-F bond proton is not easily removed due to higher electronegativity (EN) of F, more bond dissociation energy required.
Acidic nature

\propto \frac{1}{B o n d d i ssoc ia t i o n e n er g y}

So, HF is not a stronger acid than

H Cl

Q. Which of the following statement is not true?

HOCl is a stronger acid than HOBr

HF is a stronger acid than HCl

Among halide ions, iodide is the most powerful reducing agent

Fluorine is the only halogen that does not show a variable oxidation state

Due to strong H-F bond proton is not easily removed due to higher electronegativity (EN) of F, more bond dissociation energy required. Acidic nature ∝Bonddissociationenergy1​ So, HF is not a stronger acid than HCl

Acidic nature $\propto \frac{1}{B o n d d i ssoc ia t i o n e n er g y}$
So, HF is not a stronger acid than $H Cl$
