The two bonds $N=O$ and $N-O$ in $CH_3NO_2$ have the same bond length due to:

In graphite, the $C-C$ bond length $(141.5 \, pm)$ is found to be shorter than the normal $C-C$ single bond length $(154 \, pm)$. This anomaly occurs due to:

Provide the Lewis dot resonance structures of nitrogen oxides and give information about their shapes and bond parameters.

Determine the order of bond length for the $C-N$ bonds labeled as $x$,$y$,and $z$ in the given structures.

Write the resonance structures of $CO_3^{2-}$ and $HCO_3^{-}$.

Identify the species having one $\pi$-bond and the maximum number of canonical forms from the following:
