I attempted to synthesize cobalt(II)acetylacetonate but my compound looks very different from it. I posted the procedure and a somewhat failed IR spectrum. Any ideas what it could be?

Edit: I prepared solutions for UV spectroscopy and the compound dissolves well in ethanol. The solutions were initially deep purple but turned olive green over a few weeks. This has me suspecting it could be cobalt(III) acetylacetonate but my solid did not change in color.

took a 3 year gap trying out non academic path in the middle of high school but eventually came back to academia and choose chemistry as my major as out of all the major this is the most established and job ready one, but its the best of the worst, and this stops me from properly putting in efforts, i guess i will research about the job market in real life, but still the faculty expects me to make chemistry my whole life's goal when i just do not have the enthusiastic about life, this undergrad is like backup for me,

how to have the confidence to accept this as a thing i can do passively? not avoidantly but passively, i keep chasing perfection thinking i shall know and understand everything in my chemistry lab handbook from every sign to word, but before an exam all that works is a summary from ai about what the syllabus actually is about and wants me to know, yet still the crisis of confidence keeps me from making me know everything from basic

I need help solving these questions and or guidance. Any help is appreciated thank you.

Hi everyone! I’ve been tasked with proposing a mechanism for an upcoming lab for the synthesis of 3-5-dimethylpyrazole using hydrazine sulphate.

After much research I’ve managed to come up with this mechanism in the picture, which looks right to me. However 3-5-dimethylhydrazine has a hydrogen attached to one of the nitrogen’s and mine doesn’t. Any help understanding where I’ve gone wrong will be much help, thank you!

I've been trying to electron count this in the covalent method, but I'm getting differing search results on whether to consider Zn(0) as 10 or 12 electrons, based on whether the 4s2 electrons are included. I assume the 4N donate 2 each and triflate is an x type ligand.

I dont see why the molecule would kick off the oxygen as it seems pretty stable and kicking it off creates an unnecessary positive charge

Additionally, im seeing an alternate mechanism online where the alcohol oxygen is the one that attacks, is that one also valid?

Like I get that from the result we can determine if a reaction is spontaneous or not, but the definition in my textbook says "maximum amount of work a system can do as it approaches the end of the reaction." What does it mean by maximum amount of work? Other definitions are saying how much usable energy is left, which I don't really understand either.

I always assumed it to be how much energy is used during the reaction, but its wrong? If anyone could dumb it down, or just explain it in different terms it would help.

Hi everyone!

I'm currently pursuing my Master's in Chemistry at NIT Durgapur.

I'm looking to teach Chemistry online to students in Classes 11 and 12, as well as JEE aspirants.

My focus will be on building conceptual clarity, understanding the logic behind reactions, and solving problems systematically rather than just memorising

facts.

What I can help with:

Class 11-12 Chemistry

JEE Main Chemistry

JEE Advanced Chemistry

Concept building, problem-solving and doubt-clearing

I want to keep the classes interactive and adapt the teaching pace to each student's needs.

If you're interested, please DM me with your class, target exam. We can discuss the class format, schedule and fees.

Language:Hindi, English
