Question
Which of the following options are not in accordance with the property mentioned against them?
| (i) | \[\ce{F2 > Cl2 > Br2 > I2}\] | Oxidising power. |
| (ii) | \[\ce{MI > MBr > MC1 > MF}\] | Ionic character of metal halide. |
| (iii) | \[\ce{F2 > Cl2 > Br2 > I2}\] | Bond dissociation enthalpy. |
| (iv) | \[\ce{HI < HBr < HCI < HF}\] | Hydrogen-halogen bond strength. |
Solution
| (ii) | \[\ce{MI > MBr > MC1 > MF}\] | Ionic character of metal halide. |
| (iii) | \[\ce{F2 > Cl2 > Br2 > I2}\] | Bond dissociation enthalpy. |
Explanation:
Bond dissociation enthalpy order is \[\ce{Cl2 > Br2 > F2 > l2}\]
Ionic character of metal reases as electronegativity of halogen increases \[\ce{Ml < MBr < Mcl < MF}\]
