Vedclass · Answer

(A) $1$. In $XeO_3$,the structure is pyramidal with $Xe$ at the center. It has three $Xe=O$ double bonds and one lone pair on $Xe$. Each double bond consists of one $\sigma$ and one $\pi$ bond. Thus,$XeO_3$ has three $\sigma$ and three $\pi$ bonds. The statement in option $A$ is incorrect.$2$. In $XeF_4$,$Xe$ has $8$ valence electrons,$4$ are used for bonding with $F$ atoms,and $2$ lone pairs remain. Steric number = $4$ (bond pairs) + $2$ (lone pairs) = $6$,which corresponds to $sp^3d^2$ hybridization. This is correct.$3$. Argon is the most abundant noble gas in the atmosphere (approx $0.93\%$ by volume). This is correct.$4$. Liquid $He$ has a very low boiling point $(4.2 \ K)$ and is widely used as a cryogenic agent. This is correct.

Which of the following statements is $NOT$ correct?
