How can you tell that the CH2 is bonded to an oxygen straight away?

[@bobguy4727]

Using the ppm values on your data sheet

thank you so much for this!!

You're so welcome!

how do you know the peak on the infrared spectrum is C=O and not a C=C ?

[@mrmurraygreen]

Hello 👋 there are a few reasons (1) There are other bits of information in the question that lead me towards the correct functional groups. Make sure to use all the data together. (2) The range we have on the data sheet for C=C is much more narrow and so the peak appears ‘slimmer’ and is less elongated. Check out this video for an example of C=C th-cam.com/video/DQsxEPpBzmA/w-d-xo.htmlsi=s4JcQmoTiitj37cH
