Question

Br MgBr Mg diethyl ether bromobenzene phenylmagnesium bromide In this experiment, you are using 15.7 g of bromobenzene and 2.5 g of magnesiunm turnings in 50 cm3 of diethyl ether. Work out the approximate molarity of your prepared phenylmagnesium bromide solution; the total volume of your solution is 62 cm3.

Answer 1

BrMg, Ether 181 g/mol 157 g/mol Here the Mg is used in 1.04 equivalent with respect to the starting material. 7 g of reactants produce 15.7 g of reactants produce product e product 181 g 181 '15.7g -18.1 g of product 15 g g 18.1 g of product - 157 Moles of product = 18.1--=0.1 mole 181 Hence, the molarity of the solution is 0.1 M.
