Question

write anamolous properties of fluorine​

Answer 1

Answer:

Fluorine is anomalous in many properties like, ionisation enthalpy, electronegativity, enthalpy of bond dissociation that are higher than expected from the regular trends among the halogens. Its ionic and covalent radii, melting and boiling points, and electron gain enthalpy is quite lower than expected.

Reasons for the anomalous behaviour of Fluorine are:

•Small size and highest electronegativity

•Low F-F bond dissociation enthalpy

•Absence of d-orbitals
