Which of the following statementsis not true ?

Answer»

HOCl is a stronger acid than `HOBr`
HFIS a strongeracid than HCl
Among halide ions,iodine is the most powerfulreducing agent.
Fluorine is the only halogen that does not show a variable oxidation state

Solution :Due to strong H-F bond, `H^(+)` ions are not easily removed due to higher electronegativity (EN) of F Hence more bond dissociation ENERGY required.
Acidic nature `prop (1)/("Bond dissociation energy")`
So, HF is not a stronger acid than HCl.
