Vedclass · Answer

(B) $NO_2$ is an odd-electron molecule with a paramagnetic character due to the unpaired electron on the nitrogen atom. When two $NO_2$ molecules dimerize to form $N_2O_4$,the unpaired electrons on the nitrogen atoms pair up to form a weak $N-N$ single bond. In the $N_2O_4$ structure,the $N-N$ bond is relatively long and weak. Due to resonance,the four $N-O$ bonds in $N_2O_4$ become equivalent in length,each having a bond order of $1.5$.

During the formation of the dimer $N_2O_4$ from two molecules of $NO_2$,the odd electron on the nitrogen atom of each $NO_2$ molecule pairs up. What is the resulting structure?
