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.
The product of complete hydrolysis of XeF₆ in the following reaction is: XeF₆ + H₂O → ? HF
XeO₃F
- The complete hydrolysis of XeF₆ (Xenon hexafluoride) reacts with water to form XeO₃F, a fluorine-oxygen compound of xenon.
- This is a typical reaction for xenon fluorides where partial hydrolysis occurs, forming mixed oxides and fluorides.
- XeOF₄ and XeO₂F₂ are not the products of complete hydrolysis of XeF₆; they are formed in incomplete hydrolysis reactions.
- Therefore, the correct answer is (c) XeO₃F.
