Deduce the structure of the molecule. Notes: The integration ratio is 1:1:1:3:3 Protons in the region of 1.5-1.8 ppm do not have ideal J-couplings. Minor impurities (eg 1.18 & 2.4 ppm) in the proton NMR. intensity 120 80 60 40 20 0 200 180 160 140 NMR spectrum of Unknown 100 pm

Answer 1

VIII Obubled H: 18ppm. Mulilet) je

Thus, the Compound is 3-chloro-2-pentanone.

I'm sorry for the cuts while writing the Chemical shift values. So, I'm writing it again for your convenience.
