WebNov 14, 2012 · The Grignard reaction product should appear as a viscous glassy mass with a brownish color. You will need to hydrolyze the Grignard adduct by slowly adding about 10 mL of 3 M HCl with stirring (you can use a glass stirring rod or simply swirl the contents of the beaker by hand). WebThe mechanism of Grignard reagents is a bit elusive due to the inclusion of single-electron transfers, radical ions, surface-bound species, and perhaps even free radicals. 2 The R and Mg groups are covalently bond but extremely polarized, ...
