Question

Which of the following species represent organometallic compounds:

(a)BrMgC$\equiv$CCH₂CH₃ ; (b) NaOCH₂CH₃ ; (c)KOC(CH₃)₃ ; (d) PhLi?

Short answer

Answer

(a)BrMgC $\equiv$CCH₂CH₃ and (d)PhLi represent an organometallic compound.

Step-by-step solution

Step-by-Step Solution Step 1: Definition of an organometallic compound

The one or multiple carbon-metal bond(s)-containing compounds are designated as organimetallic compounds. Examples of these compounds are as follows:

• Organolithium
• Grignard reagent
• Organomagnesium

Definition of metallic bases

Metallic bases are bases that form from the reaction between a base, such as NaOH or KOH, and an acid.Bases such as sodium and potassium alkoxides represent such metallic bases.

So, from the given definitions, it is observed that :

(a) BrMgC $\equiv$CCH₂CH₃ and (d)PhLi represents an organometallic compound.

(b)NaOCH₂CH₃ and (c) KOC(CH₃)₃do not represent an organometallic compound.

Hence, (a) BrMgC $\equiv$CCH₂CH₃ and (d)PhLi represents an organometallic compound.
