Above reaction is a Baeyer Villiger rearrangement of an asymmetric ketone with magnesium mono peroxo pthalate hexahydrate (in the drawing , `Mg^(+2)` is omitted for clearity ) identify major product .

Di-tert-glycols rearrange in the presence of acid to give alpa -tertiary ketones. The trivial name of the simplest glycol of this type is pinacol, and this type of reaction therefore is named pinacol rearrangement (in this specific case, the reaction is called a pinacol-pinacolone rearrangement). The rearrangement involves 4 steps. one of the hydroxyl groups is protonated in the first step. A molecule of water is eliminated in the second step and a tertiary carbocation is formed. The carbocation rearranges in the third step into a more stable carboxonium ion via a [1,2] rearrangement. In the last step, the carboxonium ion is deprotonated and the product ketone is obtained. How many products obtained in above reaction?

24 gm pure sample of magnesium is burnt in air to form magnesium oxide and magnesium nitride. When products are treated with excess of H_(2)O , 3.4 gm of gaseous NH_(3) is generated according to given reactions. Mg+O_(2) rarr MgO Mg+N_(2)rarr Mg_(3)N_(2) Mg_(3)N_(2)+ 6H_(2)O rarr 2Mg(OH)_(2)+2NH_(3) Calculate the amount of Mg(OH)_(2) (in gm) produced in above reaction.
