How will you prepare 2-methyl-propan-2-ol from methyl magnesium bromide?Give a balance equation.

To prepare 2-methyl-propan-2-ol (also known as tert-butyl alcohol) from methyl magnesium bromide, you can perform a Grignard reaction. Here's the balanced chemical equation for the reaction:

CH3MgBr + 2 CH3CH2CHO -> (CH3)3COH + MgBr(OCH2CH3)2

In this reaction:

Methyl magnesium bromide (CH3MgBr) reacts with two moles of acetone (CH3COCH3), which is the Grignard reagent. Acetone has the structure CH3COCH3.
The Grignard reagent adds to the carbonyl group of acetone, forming an alcohol. In this case, it forms tert-butyl alcohol [(CH3)3COH].
Magnesium bromide (MgBr2) is formed as a byproduct and is often found in the reaction mixture.
Please note that Grignard reactions are typically conducted under anhydrous (water-free) conditions and in an inert atmosphere, such as under nitrogen or argon, to prevent the reaction from being quenched by moisture or oxygen. Additionally, proper safety precautions should be taken when working with Grignard reagents, as they can be highly reactive.
