Consider the following four elements, which are represented according to long form of periodic table Here W , Y and Z are left, up and right elements with respect to the element ‘ X ’ and ‘ X ’ belongs to 16 t h group and 3 r d period. Then according to given information the incorrect statement regarding given elements is

Options

  1. AMaximum electronegativity : Y
  2. BMaximum catenation property : X
  3. CMaximum electron affinity : Z
  4. DY exhibits variable covalency

Correct answer

D. Y exhibits variable covalency

Step-by-step solution

W : Phosphorus Electronegativity : O > C l > S > P Electron Affinity : C l > S > O > P Y : Oxygen X : Sulphur Catenation : S > P > O > C l Z : Chlorine Oxygen exhibits covalency of two only
