i want to know the quantity of grignard reagent in industries these days??????

Your question is not clear to me.
Let me explain you the grignard reagent
Organic compounds in which a metal atom is directly linked to carbon atom are known as organometallic compound.e.g. HC≡CNa, (C2H5)4Pb, (C2H5)2Zn

Alkyl or aryl magnesium halide (R-MgX) are also called Grignard reagents or organometallic compounds.Grignard reagent on double decomposition with water or with other compounds having active H(the hydrogen attached on O, N, F or triple bonded carbon atom are known as active hydrogen) give alkane.
