Why Grignard reagent is prepared in anhydrous conditions?
An anhydrous condition does not contain the presence of water. Since Grignard reagents are very reactive in water, the removal of water is necessary. Alkane is the product formed after this reaction. The following reaction shows the reaction of the Grignard reagent with water.
R-Mg-X+H 2 O→R-H+Mg(OH)X
