A) Electronegativity -\[P<S<N<O\]
B) Stability - \[-\,{{O}_{2}}<{{O}_{2}}^{-}<{{O}^{2-}}_{2}<\,{{O}^{\,2+}}_{2}\]
C) Dipole moment - \[\,P{{H}_{3}}<As{{H}_{3}}<Sb{{H}_{3}}<N{{H}_{3}}\]
D) Vander wall radius - \[Ne<F<O<N\]
Correct Answer: B
Solution :
Stability \[\propto \] B.D.E. \[\propto \] Bond order Stability \[{{O}^{+2}}_{2}>{{O}_{2}}>{{O}^{-}}_{2}>{{O}_{2}}^{-2}\]
