General chemistry question:
If you are given a few ounces of a liquid, how exactly, step by step, do you derive the structural formula of its molecules?

>> No.4852395

by drinking it

Start by having an autistic fit over not using metric units.

I'm sorry this isn't about qualia shoving tulpa up your ass to determine the minimum IQ to study engineering at Oxford.

I'm guessing its different for every liquid.
My knowledge on chemistry is very limited thought, I'm more of a mathguy. Will be lurking for serious answer.

Well depends what you liquid you give me, as an analytical chemist if you ask me to tell you what is in a random fluid I will first ask you questions.

But imagining I can't ask you questions for whatever reason.

LCMS to give me a rough idea of whats in it.
GCMS to quantify more precisely.
IRspec to determine bonds and from that structure.
NMR for further structure if it proves organic.
And go from there.

>>4852467
and if you supposedly could avoid all harm, would you ever try to make it react in specific conditions?
also if organic, you might wanna check chirality and such, wouldn't you? (I have very little knowledge of chemistry so I'm just trying to give ideas)
