Chemistry - CHEMICAL BONDING Question with Solution | TestHub

Calculate value of $\frac{x+y+z}{10}$ here

$x$ is value of $\mathrm{O}-\mathrm{N}-\mathrm{O}$ bond angle in ${\mathrm{NO}}_3^{-}$

$y$ is value of $\mathrm{O}-\mathrm{N}-\mathrm{O}$ bond angle in ${\mathrm{NO}}_2^{+}$

z is value of $\mathrm{F}-\mathrm{Xe}-\mathrm{F}$ bond angle (between adjacent F ) in ${\mathrm{XeF}}_4$
