Question

Below is the 1H-NMR of the starting material. Draw the structure of the product on the 1H-NMR spectra and pencil in the changes you would expect to see in the spectra. Be sure to include multiplicity where applicable. Attach the spectra to your reflection. Product is 2-butoxynapthelene aromatic H (7) OH (1) PPM

Answer 1

structure of 2-buto ay naphthalene is on Now; the aromatic multiplicity shall remain same. It is the aliphatic region that will show new beaks. Let us designate no the aliphatic brotons i ud The deshielding runs as a blend. This is due to the proximity effect of the electronegative 0чи арт Now; the multiplicity, based on (m+1) rull shall be: a : (2+1) = 3 b : (2+1) * (2+1) = 12 ie multiplet c: multiplet [ some reason as b ] di (2+1) = 3. Y due to : we show the aliphatic region 1.0 0.5 TMS 1.5 2.0 2.5 3.0 4.5 4.0 3.5 1 dl in ppm) Hope it hеlр » Чөц .
