Organic Chemistry Hantzch Synthesis

AI Thread Summary
The discussion focuses on the Hantzsch synthesis in organic chemistry, specifically addressing a homework problem related to the reaction mechanism. Participants highlight the necessity of ammonia in the reaction and debate whether to use 3-oxobutanenitrile or butanoyl cyanide as reactants. A reference to the Wikipedia page on Hantzsch pyridine synthesis is suggested for understanding the functional groups involved. The conversation emphasizes the importance of identifying the correct reactant for successful synthesis. Overall, the thread aims to clarify the mechanisms and choices in the Hantzsch synthesis process.

I know the answer has to be a or c because you need the ammonia to make this reaction happen but I don't know whether you would want to use 3-oxobutanenitrile or butanoyl cyanide. Thanks

Consider the mechanism at e.g. http://en.wikipedia.org/wiki/Hantzsch_pyridine_synthesis - can you label the various functional groups?

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...
