1. Signal Assignment. Below are a set of ranges where a specific H' NMR signal might be found. 0.5-2.0ppm 2.0-3.0ppm 3.0-5.Oppm 0.5-6.Oppm 5.0-7.0ppm 7.0-8.Oppm 9.0-10.0ppm 10.0-12.0ppm Assign to the slots above where the following highlighted protons might be found. a) CH3-CH2- b) CH-CH2-CH2- c) HC-0 d) H-C(O)-R e) H-O-R ) H-O-C(O)-R g) H;C-Ar h ) H-C-C- j) CH3-CEC ...some groups appear in the same ppm range. [2pts each group correctly assigned) 2. Signal Splitting. Decide what splitting pattern (singlet, doublet,...
