The property which is not true about Fluorine is,
- A Most of its reactions are exothermic.
- B It forms only one oxo acid.
- C Highest electronegativity.
- D High F-F bond dissociation enthalpy.
Answer & Solution
Correct Answer
(D) High F-F bond dissociation enthalpy.
Step-by-step Solution
Detailed explanation
Most of the reaction of fluorine is exothermic because fluorine in its elemental state is the most electronegative element
in the periodic table. Due to its highest electronegativity, its bond dissociation enthalpy is low. HOF is the only oxoacid of
fluorine.
in the periodic table. Due to its highest electronegativity, its bond dissociation enthalpy is low. HOF is the only oxoacid of
fluorine.
