When phenol reacts with bromine at low temperatures, the primary product formed is p-bromophenol. This occurs because the hydroxyl group on phenol directs the bromine substitution to the para position due to its activating and ortho/para-directing effects.

Reaction Details

The reaction can be summarized as follows:

Phenol Structure: The presence of the -OH group enhances electron density on the aromatic ring.
Substitution Position: Bromine tends to substitute at the para position more favorably than the ortho position at lower temperatures.

Final Product

Thus, the correct answer to the reaction of phenol with bromine at low temperatures is B. p-bromophenol.

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?
