The compound which is not organometallic is:

A)  tetraethyl lead

B)  trimethyl aluminium

C)  ethylmagnesium bromide

D)  sodium ethoxide

Correct Answer: D

Solution :

                 Key Idea: Organometallic compounds are those in which metal atom is directly attached to alkyi group. \[\underset{Ethyl\text{ }magnesium\text{ }bromide}{\mathop{{{C}_{2}}{{H}_{5}}-Mg-Br}}\,\]                 \[\underset{Sodium\text{ }ethoxide}{\mathop{{{C}_{2}}{{H}_{5}}-O-Na}}\,\] \[\because \]Na is attached to oxygen in sodium ethoxide \[\therefore \]It is not an organometallic compound.
