Question

Draw the structure using IR and HNMR

Answer 1

This is the IR, the HNMR is the first attachment

Answer 2

According to our prof, we have to figure out our unknown structure. There are 5 HNMR peaks: quartet, singlet, singlet, doublet, triplet.

For the IR, our prof confirmed we have a carbonyl group, ether, and alkane. So there must be an ester in the structure. She said there are no C=C double bonds in the structure.

I took this to a few tutors and classmates and they couldn't get the correct structure either. We worked hours on this. If you think you have it please reply ASAP.

Answer 3

Do you have the formula, or a mass spectrum?

Answer 4

Turns out I couldn't figure it out bc the prof didn't tell me my unknown was contaminated. There r supposed to be 4 instead of 5 signals. It's all good I got this solved

Answer 5

@aaronq there was no mass spec nor CNMR nor molecular formula but the prof got back to me in an email. It's all good I got it solved
