The shape of XeO₂F₂ is Trigonal bi-pyramidal see-saw tetrahedron (see attached pictures)
- As you said the hybridization of Xe here is sp³d so its geometry has to be Trigonal bi-pyramidal in which F atom located on axial positions but for the final shape we exclude lone pair on Xe to give see-saw shape (see second picture)
- Remember that we have 5 pairs (4 bond pairs + 1 lone pair) and we have to place lone pair at equatorial position.

<u>Answer:</u> The correct option is C) decomposition
<u>Explanation:</u>
Single displacement reaction is defined as the reaction where a more reactive element displaces a less reactive element from its salt solution.
Element B is more reactive than element A
Double displacement reaction is defined as the reaction where an exchange of ions takes place in a solution
Decomposition reaction is defined as the reaction where a single large chemical species breaks down into two or more smaller chemical species.
Synthesis reaction is defined as the reaction where two or more smaller chemical species combine together in their elemental state to form a single large chemical species.
For the given chemical reaction:
Here, water is breaking down into two smaller species of oxygen and hydrogen gas. Thus, it is a decomposition reaction.
Hence, the correct option is C) decomposition
