The IUPAC name of acraldehyde is commonly known as propanal. This compound is an aldehyde with the molecular formula C3H6O. It is important to recognize the structure and naming conventions used in organic chemistry.

Options Breakdown

  • (A) prop-2-en-1-al: This name refers to a different compound with a double bond.
  • (B) propionaldehyde: This is another name for propanal, making it a correct choice.
  • (C) but-2-en-1-al: This name indicates a four-carbon chain, which is not applicable here.
  • (D) propanal: This is the correct IUPAC name for acraldehyde.

Final Answer

The correct answer is (D) propanal, which is the IUPAC name for acraldehyde.

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?
