What is the type of hybridization of $Xe$ in $XeF_2$?

Explain $sp^3d^2$ hybridization with a suitable example.

In which of the following pairs of molecules/ions,the central atoms have $sp^{2}$ hybridisation?

Which statement is correct about $CO_2$ if the central atom uses $s + P_x$ orbitals in hybridization?
$(i)$ $\pi$ bond will be formed by $P_y$ and $P_z$
$(ii)$ molecule can be in $XY$ plane
$(iii)$ molecule can be in $XZ$ plane
$(iv)$ molecule can be in infinite plane
$(v)$ molecule can be in $YZ$ plane
Correct code is:

In the series ethane,ethylene and acetylene,the $C-H$ bond energy is

The number of $sp^2 - sp^2$ sigma bonds in the compound given below is
