I need some help in here please!
a) Give the major product of the following reaction
(after aqueous workup). If no reaction occurs, draw the starting
material. There are two products of this reaction. Draw the one
that contains the saturated (nonaromatic) six-membered ring.
b) Give the major product of the following reaction (after
aqueous workup). If no reaction occurs, draw the starting material.
There are two products of this reaction. Draw the one that contains
the five-membered ring.

Grignard reagent THE GRIGNARD REAGENT-PREPARATION AND REACTION In this experiment, you will prepare a Grignard reagent, phenyl magnesium bromide, from bromobenzene and magnesium metal. The Grignard reagent will then react with methyl benzoate to form triphenylmethanol. Introduction Grignard reagents, such as organomagnesium halides, were discovered in 1910 by French chemist Victor Grignard. The Grignard reaction is one of the most general methods for carbon- carbon bond formation in all of organic chemistry....

Grignard Reaction 1. Draw your complete reaction, including the formation of the Grignard reagent and the reaction with your carbonyl compound. Below each reagent, write its molecular weight and density (if a liquid). Also write how much of each material you will use in ml (if liquid), grams, and moles. Also include the molecular weight and melting point of your final product. 2. How many moles of Grignard reagent are you synthesizing? What mass of water could fully react with...

i need help with post questions, thanks
Product Isolation After stirring the reaction for 5 minutes and allowing the reaction mixture to cool (the reaction can be exothermic), remove the Claisen head from the conical vial. Slowly add 3 M HCl(aq) drop-wise. The solid may need to be broken up with a stirring rod or a pipet. Continue to add acid until the aqueous phase (bottom layer) tests positive with pH paper. Extractions can be done using the conical funnel...
