Question

Is FF Bond Strong?

Answer 1

• FF bond is not a strong bond.
• The heavy repulsion between the lone electron pairs of two fluorine atoms makes the F–F bond weak.
• Additionally, because fluorine has very low ionization energy, it can readily react with other elements and disrupt the F–F bond.
• Compared to the other group 17 elements, the bond length between the two F atoms is longer.
• The FF bond is consequently weak.

Hence, the FF bond is not strong.
