Chapter 12.2, Problem 3P

Interpretation Introduction

Interpretation:

The organometallic compound formed by excess reaction of methylmagnesium chloride with $GaC{l}_3.$

Concept introduction:

• Organometallic compound it can be defined as the compound which contain Carbon – Metal bond.
• The carbon attached to the halogen in an alkyl halide is an electrophile, whereas the carbon attached to the metal in an organometallic compound is a nucleophile.
• Transmetallation:

Transmetallation occurs when an organometallic compound is added to a metal halid whose metal is more electronegative (closer to the electronegative of carbon) than the metal in the organometallic compound.

• Grignard reagent:

The compound that results when magnesium is inserted between the carbon atom and the halogen of an alkyl halide like $\text{RMgBr \& RMgCl }$ is known as Grignard reagent.  They are also known as Organomagnesium compounds.
