Help in an analysis
I prepared an ionic liquid, it is quaternary ammonium salt. I want to check its structure through the well known
analysis methods.
the reaction is below

What analytical methods do you have available to use? These days, the standard for organic structure determination is NMR. 1-H NMR should be a good
start, and it should be relatively easy to interpret for this molecule.
Everything else (e.g., UV/Vis, FTIR, MS) is simply for confirmation. You will want to do as many of them as possible--as always, it's good to
"overdetermine" your structure. It's likely that you have a mixture of diastereomers, so you may want to use something like circular dichroism.
Also, before doing any kind of analysis/spectroscopy on your product, you will want to make sure that its pure. So, start by purifying it.
EDIT: Wait, do you have a reference for this reaction?? Your starting material is a lactam, not an amine. Unless I'm mistaken, it won't react as you
have shown here.

Yeah. I needed to look at it again today to realize the attempt to use an amide as a nucleophile. Also, Cl is a relatively crummy leaving group, as
far as they go. I was commenting on the double post. These two threads need to be merged.

So, you got an unlikely product via an impossible reaction and with nonexistent analytical evidence and don't even bother providing a reference.
Congratulations!
Please open referenceless and beginner's threads only in the proper section where I'm moving this.
