Interpreting IR Spectra

Comparison of IR spectra for methanol, methanoic acid and methanal. Using the data sheet to assign peaks/absorptions

[@shazkhan5392]

Very clear explanation of IR spectrum. Really helped.

My AS chemistry paper 2 is today, this was extremely helpful! Wish me luck :)

[@goodtimesdrift]

Same, good luck

[@MaChemGuy]

GOOD LUCK!!!!! Thanks for the comment btw

[@thatguy3221]

How did you all do?

[@annashepeleva1882]

It is very helpful! Thank you for the video!

[@MaChemGuy]

Anna Shepeleva Glad you think so. Thanks for the feedback 😊

[@katygardiner2558]

Do you know if we are expected to identify alkenes using this for the AS exam please?

[@MaChemGuy]

Never seen that before

[@katygardiner2558]

ok thank you!

[@MaChemGuy]

Normally alcohols, aldehydes, ketones, carboxylic acids

[@jazztan6160]

say if you were to run one hundred samples of methanol in the IR spectra method, would they all have identical fingerprint regions?

[@MaChemGuy]

So long as they are all pure - yes

[@jazztan6160]

cheers

[@v7phantom230]

Are we supposed to know the peak values or will that be given

[@MaChemGuy]

v7 Phantom They’re on the data sheet
