To determine which compounds can react with ammoniacal silver nitrate (AgNO3), we need to consider the nature of the compounds listed. Ammoniacal AgNO3 is commonly used to test for terminal alkynes, as they can reduce silver ions to metallic silver, forming a precipitate. Let's analyze each compound you mentioned.

Understanding the Compounds

  • 1) CH3-CH(CH3)-C≡CH (2-methyl-1-butyne): This is a terminal alkyne because the triple bond is at the end of the carbon chain. Terminal alkynes can react with ammoniacal AgNO3, producing a silver precipitate.
  • 2) HC≡CH (Ethyne or Acetylene): This is the simplest terminal alkyne. It will also react with ammoniacal AgNO3, resulting in the formation of metallic silver.
  • 3) 1-Butyne (C≡C-CH2-CH3): Like the previous two, 1-butyne is also a terminal alkyne and will react with ammoniacal AgNO3, yielding a silver precipitate.

Evaluating the Options

Now that we have identified the nature of each compound, we can conclude that all three compounds listed are terminal alkynes. Therefore, they are all capable of reacting with ammoniacal AgNO3. This means that the correct answer to your question is:

All the Above

In summary, since all the compounds you mentioned are terminal alkynes, they will all react with ammoniacal silver nitrate. This reaction is a useful qualitative test in organic chemistry for identifying terminal alkynes, as the formation of a silver mirror or precipitate indicates a positive result.

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?
