Which of the following is not the correct arrangement according to the property indicated against it ?A. `Al^(3+)ltMg^(2+)ltNa^(+)ltF^(-)` : Increasing ionic sizeB. `BltCltNltO` : Increasing first ionisation enthalpyC. `IltBrltFltCl` : Increasing electron gain enthalpy (with negative sign)D. `LiltNaltKltRb` : Increasing metallic radius |
|
Answer» Correct Answer - B `BltCltNltO`, When we move from B to O in a periodic table the first ionisation enthalpy increases due to the attraction of nucleus towards the outermost electron and I.E. of `NgtO`. |
