Which of the following are not in accordance with the property mentioned against them?
I. \(\mathrm{F}_2>\mathrm{Cl}_2>\mathrm{Br}_2>\mathrm{I}_2\) : Oxidising power
II. \(\mathrm{MI}>\mathrm{MBr}>\mathrm{MCl}>\mathrm{MF}\) : Ionic character of metal halide
III. \(\mathrm{F}_2>\mathrm{Cl}_2>\mathrm{Br}_2>\mathrm{I}_2\) : Bond dissociation enthalpy
IV. \(\mathrm{HI} < \mathrm{HBr} < \mathrm{HCl} < \mathrm{HF}\) : Hydrogen-halogen bond strength
- A I \& III only
- B II \& III only
- C I \& IV only
- D II \& IV only
Answer & Solution
Correct Answer
(B) II \& III only
Step-by-step Solution
Detailed explanation
Ionic character of metal halide :- \(\mathrm{M}-\mathrm{F}>\mathrm{M}-\mathrm{Cl}>\mathrm{M}-\mathrm{Br}>\mathrm{M}-\mathrm{I}\) This is due to low polarizability of fluorine due to very small size which gives more ionic character. Thus, II is incorrect. Order of bond…
