Chrysanthemic acid is isolated from chrysanthemum flowers. The IR spectrum of chrysanthemic acid exhibits five signals above 1500 cm-1. Identify the source for each of these signals. A. The C-C bond (expected to be ~ 1650 cm-1).
B. The O-H bond of the carboxylic acid group (expected to be 1000-1500 cm-1).
C. The vinylic C-H bond (expected to be 2000 cm-1).
D. The C-O bond of the carboxylic acid group (expected to be 1720 cm-1).
E. The C-C bond (expected to be 650 cm1 All other C-H bonds (expected to be 3000 cm-1).
F. All other C-H bonds (expected to be 2100 cm1).
G. Thе C-O bond of the carboxylic acid group (expected to be ~ 720 cm-1).
H. The O-H bond of the carboxylic acid group (expected to be 2200-3600 cm-1).
I. The vinylic C-H bond (expected to be 3100 cm-1).
