From the centesimal composition of a chemical compound we can determine its empirical formula. The molecular formula is obtained from the empirical one using the molecular mass of the compound, which can be determined by mass spectrometry.

The unsaturation index of a molecule is defined as the sum of the number of bonds \(\pi\) and the number of cycles present. Alkanes are saturated hydrocarbons as they do not contain \(\pi\) bonds or cycles and have the molecular formula \(C_nH_{2n+2}\). To calculate the unsaturation index of a compound, we only have to compare the number of hydrogens it has with those it would have if it were an alkane with the same number of carbons. This hydrogen difference divided by 2 gives us the unsaturation index.
