Question

Which of the following organometallic compound

is $\sigma$ and $\pi$ bonded?

• A. $\left[Fe\right({\eta }^5-C_5{H}_5{)}_2]$
• B. $\left[PtC{l}_3\right({\eta }^2-C_2{H}_4\left)\right]$
• C. $\left[Co\right(CO{)}_{5}N{H}_3{]}^{2+}$
• D. $Al(C{H}_3{)}_3$

Answer 1

Answer: (C)

$\left[Co\right(CO{)}_{5}N{H}_3{]}^{2+}$

$\left[PtC{l}_3\right({\eta }^2-C_2{H}_4\left)\right]$ and $\left[Fe\right({\eta }^5-C_5{H}_5{)}_2]$ are pi bonded organometallic compound.

$Al(CH_3)_3$

is sigma bonded organometallic compound.
$\left[Co\right(CO{)}_{5}N{H}_3{]}^{2+}$ is sigma and pi bonded organometallic compound.
