$XeO_3$
All the $( \mathrm{C -O} )$ bonds in carbonate ion $\left( {{\rm{CO}}_3^{2 - }} \right)$ are equal in length. - Explain.
What is not true about resonance?
How many $\sigma $ and $\pi $ bonds are there in the molecule of tetracyanoethylene
$\begin{array}{*{20}{c}} {N \equiv C} \\ {N \equiv C}\end{array}\,\,\left. {} \right\rangle C = C\,\left\langle {} \right.\,\begin{array}{*{20}{c}} {C \equiv N} \\ {C \equiv N} \end{array}$
Identify the species having one $\pi$-bond and maximum number of canonical forms from the following :
