Interpretation Introduction

(b)

Interpretation:

The synthesis of the organozinc compound from o- iodotoluene is to be predicted.

Concept introduction:

Organometallic compounds are the compounds which have an organic part and a metal part. Organozinc compounds are formed when alkyl or aryl halide reacts with zinc metals. These compounds have the least reactivity among other organometallic compounds as Grignard reagent and organolithium compounds.
