Which of the following options are not in accordance with the property mentioned against them?

(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.
