hi ,
I've a proton NMR spectra that I'm not sure how to interpret. The spectra in CDCl3 is 3.94(s, 3H) , 3.97(s, 3H) , 6.99(d, 1H) , 7.41(s, 1H) , 7.47(d, 1H) , 9.85(s, 1H)
The molecular formula is C9H10O3
I've figured out that it is an aromatic aldehyde with methoxy groups. The solution is 3,4-dimethoxy benzenecarbaldehyde. I'm just wondering why it cannot be 2,4-dimethoxy benzenecarbaldehyde
(hope I made the naming right)
