Question

Anomalous behaviour ​of fluorine is due to:​

• A. Large size
• B. Low electronegativity
• C. Low $F-F$ bond dissociation enthalpy
• D. All of the above

Answer 1

The correct option is C Low $F-F$ bond dissociation enthalpy

Anomalous behaviour ​of fluorine is due to:​
1. Small size
2. High electronegativity
3. Low $F-F$ bond dissociation enthalpy
4. Non-availability of $d$-orbitals in valence shell​
