what is grinards reaction how can propane be prepared from grinards reagent?
The Grignard reaction is an organometallic chemical reaction in which alkyl, vinyl, or aryl-magnesium halides (Grignard reagents) add to a carbonyl group in an aldehyde or ketone. This reaction is an important tool for the formation of carbon–carbon bonds.
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.
Preparation of Alkane From Grignard reagent:
(a) By action of acidic ‘H’ :
(b) By reaction with alkyl halide:
