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

(i) F_{2}> Cl_{2}> Br_{2}> I_{2}     Oxidising power.

(ii) MI > MBr > MCl > MF     Ionic character of metal halide.

(iii)  F_{2}> Cl_{2}> Br_{2}> I_{2}     Bond dissociation enthalpy.

(iv) HI < HBr < HCl < HF     Hydrogen-halogen bond strength.

Answers (1)

The answer is the option (ii, iii) The correct order of bond dissociation enthalpy is Cl_{2}>Br_{2}>F_{2}>I_{2}
There is an increase in the ionic character of metal halides with the electronegativity of halogen
MI > MBr > MCI > MF
