Which one in the following is not the resonance structure of $C{O_2}$
$O = C = O$
$^ - O - C \equiv {O^ + }$
$^ + O \equiv C - {O^ - }$
$O \equiv C = O$
Species having maximum $'Cl-O'$ bond order is
Bond length of ethane $(I),$ ethene $(II),$ acetylene $(III)$ and benzene $(IV)$ follows the order
What is correct for resonance structure ?
How many resonance forms can be written for the nitrate ion, $(NO^-_3)$ ?
All the $( \mathrm{C -O} )$ bonds in carbonate ion $\left( {{\rm{CO}}_3^{2 - }} \right)$ are equal in length. - Explain.
