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 ().

why do the isotopes of a particular element behave differently in nuclear reactions but the same in chemical reactions? chemical reactions involve changes to electrons in an atom; isotopes do not differ in electrons, and so they react the same way during chemical changes.
