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.

is Pradeep Chemistry+Ncert sufficient for all of the theory of Jee Mains Chemistry?

Hi, I’m a self-study JEE 2027 aspirant with a large 11th backlog. Since I don’t think 6–8 hour one-shots are sufficient to cover the full theory + breadth of problem types of a JEE chapter, I’ve shifted from lecture-based preparation to book-based self-study.

I have a problem with using NCERT as my primary chemistry source. In my experience, it is concise and information-heavy, but often lacks detailed explanations, systematic organisation of concepts, and categorisation of problem types. This seems especially problematic for Physical and Organic Chemistry, where I feel that simply reading NCERT may not give enough depth or problem-solving preparation.

So I’m considering this approach:

Pradeep Chemistry → complete the chapter thoroughly from Pradeep → then read NCERT for that chapter → solve JEE Main PYQs/problems.

My main question is:

Is Pradeep + NCERT sufficient as the complete theory source for JEE Main-level Chemistry?

In other words, after thoroughly completing a chapter from Pradeep and then NCERT, can I consider the theory part of that chapter complete for JEE Main, with only PYQs/problem practice remaining?

I’m asking specifically about JEE Main level, not Advanced.

Also, if Pradeep is not sufficient, what specific gap does it leave, and what would you recommend as a better book-based alternative for self-study?
