NMR problem

Can someone help me with this? I already spent 2 hours on this.
1.4 ppm, multiplet, 1H
2.5 ppm, singlet, 1H
3.7 ppm, doublet, 4H
7.3 ppm, singlet, 10H
Formula C15 H16 O
My teacher doesn't want me to have more information than necessary, therefore NMR is all I am allowed to have
THANKS.

Have you checked a spectral database? http://www.aist.go.jp/RIODB/SDBS/cgi-bin/direct_frame_top.cgi?lang=eng

12,12-dimethyl-4,6,8,10-tetra-tridecyn-3-ol, something I through together that I'm still trying to check. The IUPAC may be a little off but your carbon count is friggin' high.

From 10 H singlet in aromatic region, I think there are 2 benzene rings attached to a carbon.

That would explain the unsaturation and the H way the heck down field (probably an OH). Also gives symmetry again pointing to 10H singlet.

That wasn't nice of your teacher to withhold IR, but I'm thinking your molecule might be 1,1-diphenyl-2-propen-1-ol. Let me know what you think.

I think your hydrogen count is off, but thanks for the help. I think the formula should be 1,3-dimphenyl-2-propanol.

that site was my lifeline in orgo lab. hope we don't need nmr in rx school, cuz i don't remember anything.

from what i remember, my organic professor said nmr, mass spec, IR, etc. are used regularly by chemistry majors so they have to learn it really well.

Ditto, I haven't used any of that info since I graduated (Chem major), and I work in an analytical lab. Surely we would be able to pick it back up quickly if needed; hopefully, it's not.
