Can you show the mechanism thank you!!!
Devise 2 different syntheses(list the starting materials and any reagents) of 3-methyl-3-pentanol. Each syntheses must involve a Grignard reagent.

Starting with acetylene use a sequence of reagents to show how you could make each of the following products. Note that some steps will be redundant so please just start from a common intermediate once you have shown its synthesis. For example, all of the other products can be made from either 1-butyne or 2-hexyne. You may not use any other source of C other than methyl bromide, calcium carbide, chloroform and the products you can make from these sources....

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....
