$\mathrm{Fe}\left(\mathrm{CO}{)}_5\stackrel{2\mathrm{NO}}{⟶}\mathrm{Fe}\right(\mathrm{CO}{)}_2(\mathrm{NO}{)}_2+3\mathrm{CO}$

Select the incorrect statement(s) regarding the above reaction.

$\mathrm{Fe}\left(\mathrm{CO}{)}_5\stackrel{2\mathrm{NO}}{⟶}\mathrm{Fe}\right(\mathrm{CO}{)}_2(\mathrm{NO}{)}_2$

dsp³, trigonal bipyramidal        sp³, tetrahedral

d⁸ configuration zero                d¹⁰configuration, zero unpaired e^-

unpaired electron            O. No. of Fe = -2

  O. No. of Fe = 0              O. No of N⁺= +1

NO is 3e^- donating in nature

$\mathrm{NO}\to {\mathrm{NO}}^{+}+{\mathrm{e}}^{-}$

 N⁺ donate one e^- pair to Fe.

 EAN    $\mathrm{Fe}(\mathrm{CO}{)}_5=26+(5\times 2)=36$

$\mathrm{Fe}\left(\mathrm{CO}{)}_2\right(\mathrm{NO}{)}_2=26+2+(2\times 2)+(2\times 2)=36$
