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

Comment on the nature of two $S-O$ bonds formed in $SO_{2}$ molecule. Are the two $S-O$ bonds in this molecule equal?

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

The correct statement$(s)$ about $O_3$ is (are)
$A$. $O-O$ bond lengths are equal.
$B$. Thermal decomposition of $O_3$ is endothermic.
$C$. $O_3$ is diamagnetic in nature.
$D$. $O_3$ has a bent structure.

How many resonance structures are there for anthracene?

$CH_2 = O \leftrightarrow \overset{\oplus}{C}H_2 - \overset{\ominus}{O} \leftrightarrow \overset{\ominus}{C}H_2 - \overset{\oplus}{O}$
Which of these structures is practically not a valid canonical structure for formaldehyde?
