The Correct Option is C

Solution and Explanation

Partial hydrolysis of $X e F _{6}$ gives $X e O F _{4}$ (compound $X$ ) $X e F _{6}+ H _{2} O \rightarrow X e O F _{4}+ 2 H F$
$XeF _{6}$ reacts with silica $SiO _{2}$ to form $XeOF _{4}$ (compound $X$ ) $2 X e F _{6}+ S i O _{2} \rightarrow 2 X e O F _{4}+ S i F _{4}$

P-Block Elements

  • P block elements are those in which the last electron enters any of the three p-orbitals of their respective shells. Since a p-subshell has three degenerate p-orbitals each of which can accommodate two electrons, therefore in all there are six groups of p-block elements.
  • P block elements are shiny and usually a good conductor of electricity and heat as they have a tendency to lose an electron. You will find some amazing properties of elements in a P-block element like gallium. It’s a metal that can melt in the palm of your hand. Silicon is also one of the most important metalloids of the p-block group as it is an important component of glass.

P block elements consist of:
