Perform stoichiometric calculations to obtain 1 ml of
the final product, using the concept of limit reagent in the
synthesis of geranial and phenylmagnesium bromide. assuming 100%
yield.
The complete equations of the synthesis of geranial and
grignard reagent are shown below. (They are needed to calculate the
final 1 ml of product of the reaction above)
