Question
The unsaturation number or degree of unsaturation (U) can be used to determine the number of rings and multiple bonds in a compound from its molecular formula. Given a structure, you can determine the number of hydrogens without having to count them explicitly. Consider three compounds and their degree of unsaturation.
