CHXI03:CLASSIFICATION OF ELEMENTS AND PERIODICITY IN PROPERTIES

313405 The order that is not in accordance with the property stated against it is

1

F_{2} > C l_{2} > B r_{2} > I_{2}

:Oxidising power

2

H I > H B r > H C l > H F

: Acidic property in water

3

F_{2} > C l_{2} > B r_{2} > I_{2}

: Electronegativity

4

F_{2} > C l_{2} > B r_{2} > I_{2}

: Bond dissociation energy

Explanation:

Bond dissociation energy is in the order $C l_{2} > F_{2} > B l_{2} > I_{2}$ because of repulsion between lone pairs in F atoms due to small size.
