Which one in the following is not the resonance structure of $C{O_2}$
Polarization of electrons in acrolein may be written as
A molecule may be represented by three structures having energies $E_1 , E_2$ and $E_3$ , respectively. The energies of these structures follow the order $E_3 < E_2 < E_1$ , respectively. If the experimental bond energy of the molecule is $E_0$ , the resonance energy is
In the cyanide ion, the formal negative charge is on
