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.

IR (Infrared) spectrum is used to determine the functional groups in the molecule, by measuring the vibrations of the atoms.

The structure of chrysanthemic acid is shown in the picture.

The five signals of chrysanthemic acid which are above the are:

1. The vinylic bond ().

2. The bond ().

3. The bond of carboxylic acid ()

4. The bond ()

5. All other bonds ().
