Question

Which of the following is an organometallic compound ?

• A. Lithium methoxide
• B. Lithium acetate
• C. Lithium dimethylamine
• D. Methyl lithium

Answer 1

Answer: (D)

Organometallic compounds are those in which metal is linked directly with carbon.

(a) $\underset{\text{lithium methoxide (no metal-C bond)}}{C{H}_{3}ONa}$

(b) $\underset{\text{(lithium acetate) (no metal-C bond)}}{C{H}_{3}COOLi}$

(c) $\underset{\text{lithium dimethylamine (no metal-C bond)}}{(C{H}_3{)}_2^{-}NHLi}$

(d) $\underset{\text{methyl lithium (metal-C bond is present)}}{C{H}_{3}Li}$

Hence, methyl lithium due to the presence of metal-carbon bond, is an organometallic compound.
