Identify the absence or presence of two significant bands in the IR spectra of isoamyl alcohol and isoamyl acetate that indicate an esterification has occured.
Identify the absence or presence of two significant bands in the IR spectra of isoamyl alcohol and isoamyl acetate that indicate an esterification has occured.
Homework Answers
In the first spectra, we can observe alcohol stretching O-H stretching frequency 3328 cm-1.
In the second spectra, we can observe O-H stretching's disappearance, and new peaks appear at 1743 cm-1. It indicates that the C=O stretching of ester has formed.

The reaction is Esterification Acetic Acid + isoamyl alcohol yielding isoamyl acetate During the extraction indicate which substance(s) is (are)) removed at each step with the following reagents: a. washing with water b. washing with saturated sodium bicarbonate. Since the reaction you will perform is reversible, give two ways you could push the equilibrium in the forward direction in the laboratory.
