Propose a chemical formula for the white solid that forms during the initial stages of the reaction of Sn with benzyl chloride
In my inorganic class, we carried out the synthesis of chlorotribenzyltin, $\ce{SnCl(CH2C6H5)3}$.
The synthesis begins with a reflux I'll describe below:
In a hood, place 2.0 g (17 mmol) of 325 mesh ...
