1.	Which of the following options are not accordance with the property mentioned against them? (a) `F_(2)gtCl_(2)gtBr_(2)gtI_(2)` Oxodising power (b) `MIgtMBrgtMClgtMF` Ionic character of metal halide (c ) `F_(2)gtCl_(2)gtBr_(2)gtI_(2)` Bond dissociation enthalphy (d) `HIltHBrltHClltHF` Hydrogen - halogen bond strength
Answer» Correct Answer - B::C `F_(2)gtCl_(2)gtBr_(2)gtI_(2)` As ability to gain electron increases oxidising property increases. Here, F is the most electronegative element having highest value of SRP hence it has highest oxidising power. `MIgtMBrgtMClgtMF` This is the incorrect order of ionic character of metal halide. Correct order can be written as `MIltMBrltMClltMF` As electronegativity difference between metal and halogen increases ionic character increases. `F_(2)gtCl_(2)gtBr_(2)gtI_(2)` This is incorrect order of bond dissociation energy . Correct order is `Cl_(2)gtBr_(2)gtI_(2)` due to electronic repulsion among lone pairs in `F_(2)` molecule.
