Chem Lab II midterm unit 7

to hydrolyze the salt formed in the reaction of the Grignard reagent, you added

3M HCL soln

difference between % recovery and % yield

physical change, chemical change

difference between % crude yeild and % pure yeild

yield of rxn products before purification, yield of rxn products after purification

if you wanted to was a water soluble by product from a reaction mixture, you would

extract with 10% sodium bicarbonate solution

what was the purpose of dispensing the initial reagents with syringes

prevent moisture in reactants mixutre

purpose of cold water on outside of reaction vessel, why is it needed?

to cool grignard reagent before addition, the addition is exothermic?

if benzaldehyde was added too quickly

solvent would boil, mixture would sputter, product would be lost

organic by product

biphenyl
