Which one of the following orders is not in accordance with the proper

1.	Which one of the following orders is not in accordance with the property stated against it ?
Answer» `HI gt HBR gt HCL gt Hf` :Acidic property in water `F_2 gt Cl_2 gt Br_2 gt I_2` : Electronegativity `F_2 gt Cl_2 gt Br_2 gt I_2` : Bond DISSOCIATION energy `F_2 gt Cl_2 gt Br_2 gt I_2`: oxidising power Solution :Bond dissociation energy of fluorine is less because of its SMALL size and repulsion between electrons of two atoms. So option (C) is wrong order. The CORRECT order is : `[Cl_2 gt Br_2 gt F_2 gt I_2]`
