### What is Meant by Degree of Unsaturation?

The Degree of Unsaturation is defined as the sum of the number of the rings involved plus the total number of multiple bonds present in an organic compound. The molecular formula is abridged to CnHm and the degree of unsaturation formula is given by
Degree of Unsaturation = (Total Number of Double Bonds) + (2 x Total Number of Triple Bonds) + (Total Number of Rings)
The notion of the degree of unsaturation of an organic compound is derived simply from the tetravalency of carbon. Any compound whose chemical formula has two hydrogens less than the maximum number possible (2n+2) must have one ring or one double bond.
Example:
Calculate the degree of unsaturation for benzene.
Solution:
Benzene is a cyclic compound with one ring and three double bonds.
Hence, the degree of unsaturation for benzene is:
Degree of Unsaturation = 3 + 0+ 1= 4
