A Grignard reagent has a formula RMgX where X is a halogen, and R is an alkyl or aryl (based on a benzene ring) group. For the purposes of this page, we shall take R to be an alkyl group.
A typical Grignard reagent might be CH3CH2MgBr.

The gridnard reagent is an oragnochemical reaction in which alkyl,vinyl,or aryl,-magneaium halides add to a carbonyl group in an aldehyde or ketone.This reaction is an important tool for the formation of bonds between two carbon atoms.The reaction of an organic halide with magnesium is not a Grignard reaction, but provides a Grignard reagent.
