Question

Among the elements of group 17, fluorine is the most reactive owing to its:

• A. Electronegativity and small size of atom
• B. Extremely low oxidizing power and high dissociation energy of F-F bond
• C. Due to high ionization energy
• D. Large size of the atom

Answer 1

The correct option is B

Extremely low oxidizing power and high dissociation energy of F-F bond

Among the elements of group 17, fluorine is the most reactive owing to its electronegativity and small size of atom.Also extremely high oxidizing power and low dissociation energy of F-F bond is responsible for its reactivity.
