Vedclass · Answer

(A) The acetylide ion is $C_2^{2-}$.Total number of electrons in $C_2^{2-} = (6 	imes 2) + 2 = 14 \ e^-$.According to Molecular Orbital Theory,the electronic configuration of $C_2^{2-}$ is $\sigma 1s^2, \sigma^* 1s^2, \sigma 2s^2, \sigma^* 2s^2, \pi 2p_x^2 = \pi 2p_y^2, \sigma 2p_z^2$.Bond order $= \frac{1}{2} (N_b - N_a) = \frac{1}{2} (10 - 4) = 3$.Since all electrons are paired,it is diamagnetic.Now,check $NO^{+}$: Total electrons $= 7 + 8 - 1 = 14 \ e^-$.$NO^{+}$ also has a bond order of $3$ and is diamagnetic.Therefore,the properties match $NO^{+}$.

The bond order and magnetic property of acetylide ion are same as that of $........$.
