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.

Answer 1

(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  \[\ce{Ml < MBr < Mcl < MF}\]
