Question

Nerol is an optically inactive isomer of geraniol and is found in many essential oils that can be extracted from plants and flowers. It has the odor of sweet rose and high resolution mass spectrometry gives an molecular ion at M⁺ = 154.1347

(The order of atoms should be carbon, then hydrogen, then the others in alphabetical order.)

Calculate the degree of unsaturation for this compound

Answer 1

1 ) formula : C10H18O

degree of unsaturation = DoU = 2C + 2 - H / 2

                                           = 2 x 10 + 2 - 18 / 2

                                           = 2
