To solve this question, we need to understand the reaction involving N-ethyl phthalimide.

**N-Ethyl phthalimide** is a chemical compound where the ethyl group is attached to the nitrogen of the phthalimide structure.

When **N-ethyl phthalimide** undergoes hydrolysis, it reacts with water, usually in the presence of an acid or a base, to yield different products. The process is often carried out via a reaction known as the **phthalimide synthesis**.

Here’s a step-by-step explanation of the hydrolysis process:

1. **Hydrolysis of N-Ethyl Phthalimide:**
N-Ethyl phthalimide can be hydrolyzed under acidic or basic conditions to yield **ethylamine** and **phthalic acid**.

The general reaction is:
\[ \text{N-ethyl phthalimide} + \text{H}_2\text{O} \rightarrow \text{ethylamine} + \text{phthalic acid} \]

2. **Phthalic Acid Formation:**
During hydrolysis, the phthalimide ring breaks, and the product is phthalic acid. This occurs due to the acidic or basic hydrolysis conditions.

3. **Ethylamine Formation:**
The N-ethyl group on the phthalimide is converted into ethylamine during this hydrolysis.

**Conclusion:**
Upon hydrolysis, N-ethyl phthalimide yields **ethylamine** and phthalic acid. Thus, the correct answer is:

**B. Ethyl amine**

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?
