Q. Which of the following is correctly matched?
Coordination Compounds
A
Column-I - $\left[ Cr ( CO )_6\right]$ ,Column-II - Paramagnetic , Column-III - Octahedral, $s p^3 d^2$
B
Column-I - $\left[ Fe ( CO )_5\right]$ ,Column-II - Paramagnetic , Column-III - Trigonal bipyramidal, $s p^3 d$
C
Column-I - $\left[ Co ( CO )_4\right]$ ,Column-II - Paramagnetic , Column-III - Square planar, $d s p^2$
D
Column-I - $\left[ Ni ( CO )_4\right]$ ,Column-II - Diamagnetic , Column-III - Square planar, $d s p^2$
Solution:
$\left[ Co ( CO )_4\right] \rightarrow$ Paramagnetic, $d s p^2$ (square planer)
