$O_2$

Vedclass · Answer

(C) The molecule is $O_2$. $1$. $O_2$ has two unpaired electrons in its antibonding $\pi^*{2p}$ orbitals, which corresponds to a $2$-electron magnetic moment (paramagnetic). $2$. The one-electron reduced species is the superoxide ion $(O_2^-)$ and the two-electron reduced species is the peroxide ion $(O_2^{2-})$. Both can act as oxidizing and reducing agents. $3$. When $O_2$ is one-electron oxidized, it forms the dioxygenyl cation $(O_2^+)$. In $O_2$, the bond order is $2.0$ (electrons in antibonding orbitals). Removing one electron from the antibonding orbital increases the bond order to $2.5$, which causes the bond length to decrease.
