Coordination Compounds Ques 84
84. Which of the following organometallic compound is $\sigma$ and $\pi$ bonded?
[2001]
(a) $[Fe(\eta^{5}-C_5 H_5)_2]$
(b) $Fe(CH_3)_3$
(c) $K[PtCl_3(\eta^{2}-C_2 H_4)]$
(d) $[Co(CO)_5 NH_3]^{2+}$
Show Answer
Solution:
- (d) In metal carbonyl complexes, $\sigma$ and $\pi$ both bonds are present because of synergic bonding. Thus, $[Co(CO)_5(NH_3)]^{2+}$ has $\sigma$ and $\pi$ bonding.
