Ncert Exercises & Solutions

Which of the following options are correct for ${[F e {(C N)}_{6}]}^{3 -}$ is:

a. $d^{2} s p^{3}$ hybridisation

b. $d^{2} s p^{2}$ hybridisation

c. Paramagnetic

d. Diamagnetic

Choose the correct option:

1.	(a, b)	2.	(b, c)
3.	(c, d)	4.	(a, c)

According to VBT, the molecular orbital electronic configuratio of Fe

^{3 -} i n {[F e {(C N)}_{6}]}^{3 -}

Huybridisation = $d^{2} s p^{3}$

Number of unpaired electron =1

Hence, correct choices are options (a) and (c).
