Question

The correct order of bond dissociation enthalpy of halogens is : (A) Cl 2> F 2> Br 2> I 2 (B) I 2> Br 2> Cl 2> F 2 (C) Cl 2> Br 2> F 2> I 2 (D) F 2> Cl 2> Br 2> I 2

Correct order of bond dissociation enthalpy of halogens is Cl 2> Br 2> F 2> I 2. Due to inter electronic repulsions F - F bond becomes weak and easily broken.

Q. The correct order of bond dissociation enthalpy of halogens is :

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

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

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

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

Correct order of bond dissociation enthalpy of halogens is $C l_{2} > B r_{2} > F_{2} > I_{2}$ .
Due to inter electronic repulsions $F - F$ bond becomes weak and easily broken.

Q. The correct order of bond dissociation enthalpy of halogens is :

Cl2​>F2​>Br2​>I2​

I2​>Br2​>Cl2​>F2​

Cl2​>Br2​>F2​>I2​

F2​>Cl2​>Br2​>I2​

Correct order of bond dissociation enthalpy of halogens is Cl2​>Br2​>F2​>I2​. Due to inter electronic repulsions F−F bond becomes weak and easily broken.

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

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

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

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

Correct order of bond dissociation enthalpy of halogens is $C l_{2} > B r_{2} > F_{2} > I_{2}$ .
Due to inter electronic repulsions $F - F$ bond becomes weak and easily broken.
