Question is based on the following passage:

p-block elements are placed in groups 13 to 18 of the periodic table. Group 15 is nitrogen family. Nitrogen makes various compounds like NH₃, HNO₃, N₂O, NO₂ etc. Phosphorus exists in the form of white and red phosphorus. White phosphorus glows in dark. PH₃ gas is used as smoke screen. Group 16 is called oxygen family. Dry air contains 21% O₂ gas by volume. Combined sulphur exists as sulphates such as gypsum, epsome salt, baryte etc. The allotropic forms of sulphur are Rhombic and monoclinic sulphur. S₂ is paramagnetic like O₂ and it is stable at high temperature. Group 17 is Halogen family. F₂ is highly reactive, Cl₂ is greenish yellow gas. Both SO₂ and Cl₂ are used for bleaching. Group 18 is Noble gas family but some noble gases also form compounds. Complete hydrolysis of XeF₆ gives HF and XeO₃ as main products.
