Question

Which of the following is/are an organometallic compound?

• A. $RMgX$
• B. $Pb(C{H}_3{)}_4$
• C. $\left[\right(C{H}_3{)}_{2}Cu]L{i}^{+}$
• D. $C_2{H}_{5}ONa$

Answer 1

Answer: (A), (B), (C)

$\left[\right(C{H}_3{)}_{2}Cu]L{i}^{+}$

Organometallic compounds are those compounds in which metal atom is directly bonded with C-atom.
Organometallic compounds contain at least one bond between a carbon atom of an organic compound and a metal.

Following are the examples of organometallic compounds:
$RMgX,(C_2{H}_5{)}_{2}Zn,(C{H}_3{)}_{4}Sn,\left(C_2{H}_5{)}_{4}PbA{l}_2\right(C{H}_3{)}_6,\&Pb(C{H}_3{)}_4,[\left(C{H}_3{)}_{2}Cu\right]L{i}^{+}etc$
$C_2{H}_{5}ONa$ is not an organometallic compound as it does not have metal-carbon bond. Hence, compounds (a), (b) and (c) are organometallic compounds.
