Q. The bond dissociation energy of Cl_{2},Br_{2} and I_{2} follow
A) Cl_{2}>I_{2}>Br_{2}
B) I_{2}>Br_{2}>Cl_{2}
C) I_{2}=Cl_{2}=Br_{2}
D) Cl_{2}>Br_{2}>I_{2}
Explanation
(d)
The bond dissociation energy of Cl_{2}, Br_{2,}and I_{2}is as
Molecule : Cl_{2} > Br_{2} >I_{2}
Dissociation :242.6 192.8 151.1
Enthalpy $(kJ\ mol^{- 1})$
