Question

can someone tell me if isoamyl acetate is pure on this IR spectrum. why or why not?

Answer 1

IR spectrum of isoamyl acetate is very pure , this is due to the fact that a broad peak of -OH group around 3400-3600 cm-1 of the starting precursors or starting materials is compleatly absent.Neither acid nor isoamyl alchol -OH groups is present in your IR spectrum. Besides , an intense peak around 1742 cm-1 for ester carbonyl further authenticates the given structure.
