Propose a molecular formula for rose oxide, a rose-scented compound isolated from roses and geraniums, which contains the elements of C, H, and O, has two degrees of unsaturation, and a molecular ion in its mass spectrum at m/z = 154.


Expert Answer

Step 1

Use the rule of thirteen to calculate the molecular formula for compound with known molecular mass.

Steps to be followed to calculate the molecular formula are as follows:

  • Find the base formula by dividing the molecular mass by 13 (sum of the masses of one carbon atom and one hydrogen atom)
