Propose a chemical formula for the white solid that forms during the initial stages of the reaction of Sn with benzyl chloride
Turned in this report and my professor commented with his thoughts
$$\ce{Sn + 2RCl \rightarrow R2SnCl2 \rightarrow R2Sn }\text{ (white solid)} \ce{+ SnCl2 \rightarrow  R3SnCl}$$
but I didn't get the question wrong. So unless if someone contributes another answer, I'll accept this as the answer.
