1. Benzene is often produced as a side product during Grignard reactions where phenylmagnesium bromide is used as the Grignard reagent. How can its formation be explained? Please include a balanced chemical equation that describes its formation.
2. Why, after the reaction is complete, is it necessary to do an extraction of the ether layer with sodium hydroxide? Please include a balanced chemical equation that represents this extraction.
