(i) F2 > Cl2 > Br2 > I2 – Oxidising power.
(ii) MI > MBr > MCl > MF – Ionic character of metal halide.
(iii) F2 > Cl2 > Br2 > I2 – Bond dissociation enthalpy.
(iv) HI < HBr < HCl < HF – Hydrogen-halogen bond strength.
Correct Answers:
(ii) MI > MBr > MCl > MF Ionic character of metal halide.
(iii) F2 > Cl2 > Br2 > I2 Bond dissociation enthalpy.
Explanation:
1. MI > MBr > MCl > MF does not match the property of ionic character of metal halide.
2. F2 > Cl2 > Br2 > I2 does not match the property of bond dissociation enthalpy.
