Question

Among the following which is not the $\pi$-bonded organometallic compound

• A. $K \left[ PtCl _{3}\left(\eta^{2}- C _{2} H _{4}\right)\right]$
• B. $Fe(\eta^5-C_5H_5)_2$
• C. $Cr(\eta^6 -C_6 H_6)_2$
• D. $(CH_3)_4Sn$

Answer 1

Answer: (D)

$(CH_3)_4Sn$

Answer 2

In $(CH_3)_4$ Sn (organometallic compounds of tin) single bonds are present in form of sigma bond, pi-bonded organometallic compound includes organometallic compounds of alkenes, alkynes and some other carbon containing compounds having pi-electrons in their molecular orbitals.
