I've been trying to figure out these NMR readings of an aldol (alpha beta unsaturated carbonyl compound), and I can't seem to get the structure. To make matters more difficult, my teacher didn't supply me with the chemical formula...just that the aldehyde has no alpha hydrogens and is aromatic.
Here are the readings...and with my interpretations that I've come up with.
7.4 doublet 2H (para substituted benzene)
7.2 doublet 2H (para substituted benzene)
6.9 singlet 1H (double bond)
2.5 singlet 3H (methyl group either next to carbonyl or double bond)
2.1 singlet 3H (methyl group either next to carbonyl or double bond)
1.9 septet 1H (hydrogen in between these two identical methyl groups)
0.9 doublet 6H (two identical methyl groups)
But for some reason, I cant structure and combine it all correctly to make it an actual product.
Your help is greatly appreciated.
