1 P – Block Elements
Which one of the following arrangements does not truly represent the property indicated against it?
1) Br2 < Cl2 < F2 : Oxidising power
2) Br < Cl < F : Electronegativity
3) Br < F < Cl : Electron affinity
4) Br2 < Cl2 < F2 : Bond energy
Solution: Br - Br 158 KJmol-1 Cl -Cl 210 KJmol-1 F- F 126 KJmol-1
Thus, F2 < Br2 < Cl2
