Question

artificial flavour for orange is obtained from:

1. amyl acetate 2. isoamyl valerate 3. melhyl butyrate 4. octyl acetate

Answer 1

4. Octyl acetate

is the answer.

Most of the natural flavor is normally quite complex, with dozens or hundreds of chemicals interacting to create the taste/smell. But fruit flavors -- have just one or a few dominant chemical components that carry the bulk of the taste/smell signal. Many of these are esters. The ester called Octyl Acetate (CH3COOC8H17) is a fundamental component in orange flavor.

Answer 2

4) octyl acetate
