Question is based on 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 , etc. Phosphorus exists in the form of white and red phosphorus. White phosphorus glows in dark. , gas is used as smoke screen. Group 16 is called oxygen family. Dry air contains 21% 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. is paramagnetic like , and it stable at high temperature. Group 17 is Halogen family. is highly reactive, , is greenish yellow gas. Both , and are used for bleaching. Group 18 is Noble gas family but some noble gases also form compounds. Complete hydrolysis of , gives HF and , as main products.
