Which one of the following orders is not in accordance with the property stated against it?
A
: Bond dissociation energy
B
: Oxidising power
C
: Acidic property in water
D
: Electronegativity
Text Solution
Verified by ExpertsThe correct answer is:
A
bond: F ‐ F CI ‐ CI Br ‐ Br I ‐ I Bond dissociationenergy (kcal/mol): 38 57 45.5 35.6 The lower value of bond dissociation energy of fluorine is due to the high inter ‐ electronic repulsion between non ‐ bonding electrons in the 
‐ orbitals of fluorine. As a result, F ‐ F bond is weaker in comparison to CI ‐ CI and Br ‐ Br bonds.
