Taking into account hybridization and resonance effects,rank the following $C-O$ bonds in order of decreasing bond length. The structure provided is the carbonate ion $(CO_3^{2-})$.

Draw the possible resonance structures for $CH_3 - \ddot{O} - CH_2^+$ and predict which of the structures is more stable. Give reason for your answer.

Despite having an unpaired electron,the $ClO_2$ molecule does not undergo dimerization because .................

Which of the following statements are true for the nitrate ion $(NO_3^-)$?
$(a)$ The coordination number of $N$ is $3$,and the structure is trigonal planar.
$(b)$ The formal charge on $N$ is $+1$.
$(c)$ The average formal charge on each $O$ atom is $-2/3$.
$(d)$ The average bond order of the $NO$ bond is $4/3$.
$(e)$ All $NO$ bond lengths are identical due to resonance.
Select the correct code:
