Please help with these two questions regarding NMR, thanks!
1. In a proton NMR, a specific carbon atom has 2 protons attached directly to it, and its neighbor carbon has 3 and another neighbor carbon has 1; what is the multiplicity of this?
3. Below is shown the spectra of C4H4O, with a mass of 68amu (if your structure’s mass adding up has some decimals left over this is fine). Your job is to write the structure of it based on this information.
Above is the proton spectra and below is the carbon spectra. The proton peaks are both singlets, yet one is 3 times larger than another: this is a big clue to the structure.
