How does adding a small amount of a Grignard reagent solution to a Grignard reaction help the reaction get started? Hint: The presence of water (moisture) is a major reason a Grignard might not start. Write the reaction that would lead to formation of propane from the Grignard reagent formed from 2-bromopropane.
