Chemistry - CHEMICAL BONDING Question with Solution | TestHub

The $\mathrm{N}-\mathrm{O}$ bond lengths in ${\mathrm{NO}}_2^{-},{\mathrm{N}}_2{\mathrm{O}}_4$ and ${\mathrm{NO}}_2$ are nearly same

$\mathrm{N}-\mathrm{O}$ bond length in ${\mathrm{NO}}_2^{-},{\mathrm{NO}}^{+}$and ${\mathrm{NO}}_3^{-}$is in the order ${\mathrm{NO}}^{+}<{\mathrm{NO}}_2^{-}<{\mathrm{NO}}_3^{-}$

The C-O bond energy in, CO, CO₂ and CO₃^2- is in the order CO $>{\mathrm{CO}}_2>{\mathrm{CO}}_3^{2-}$

$\mathrm{O}-\mathrm{O}$ bond length in ${\mathrm{O}}_3$ is greater than in ${\mathrm{O}}_2$
