Which of the following is the correct order with respect to the property indicated? (1) Cl > F (Ionisation energy) (2) K2O > Na2O > Al2O3 (Basic nature) (3) K > Na > Al > Mg (Metallic character) (4) None of these

Answer (2) Sol.      F > Cl :    Fluorine has higher first ionisation energy than chlorine due to its smaller atomic size, leading to greater effective nuclear charge and tighter hold on the valence electron despite higher electron-electron repulsion in F. The given order Cl > F is incorrect. tThe actual order is […]
