"WebGrignard reagents are used synthetically to form new carbon–carbon bonds. A Grignard reagent has a very polar carbon–magnesium bond in which the carbon atom has a partial negative charge and the metal a partial positive charge. The polarity of the carbon–magnesium bond is opposite that of the carbon–halogen bond of haloalkanes. " - Grignard reagent mcat
