What is the structure of C14H12 with mw 180 based on the data given?
I realize the structure on there is wrong but I am having trouble interpreting the 1H NMR. I don't have much experience with 13C or 1H NMR and our professor does not explain this very well. Could someone please explain the significance of dublets and quartets in 1H NMR? Thank-you!
