Vedclass · Answer

(D) Diamagnetic species are those which have all electrons paired in their molecular orbitals. $(i)$ $NO$: Total electrons $= 7+8=15$. It has an unpaired electron in the $\pi^* 2p_x$ orbital,so it is paramagnetic. $(ii)$ $NO_2$: Total electrons $= 7+8+8=23$. It has an odd number of electrons,so it is paramagnetic. $(iii)$ $O_2$: Total electrons $= 16$. According to Molecular Orbital Theory,it has two unpaired electrons in the $\pi^* 2p_x$ and $\pi^* 2p_y$ orbitals,so it is paramagnetic. $(iv)$ $CO_2$: Total electrons $= 6+8+8=22$. The structure is $O=C=O$. All electrons are paired in bonding and lone pair orbitals,making it diamagnetic.
