Description

The degree of unsaturation of a chemical can be estimated from its chemical formula.


Parameters:

(1) number of atoms with valence 1

(2) number of atoms with valence 2

(3) number of atoms with valence 3

(4) number of atoms with valence 4

(5) number of atoms with valence 5

(6) number of atoms with valence 6

(7) number of atoms with valence 7

 

degree of unsaturation =

= 1 + (0.5 * CUMULATIVE SUM((number of atoms at each valence)*((valence)-2)))
