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.

(a) A compound A has the molecular formula C7H13ClN2OC7⁢H13⁢ClN2O. How many rings and/or π bonds does it contain?

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. (a) A compound A has the molecular formula C₂H₁3CIN₂O. How many rings and/or bonds does it contain? 13 U = (b) Inspect the skeletal structure of 17a-ethynylestradiol and determine the number of hydrogens without counting them explicitly. (Hint: the compound has 20 carbons) HO HO 17a-ethynylestradiol (a synthetic estrogen used in oral contraceptives) Can compound A contain a triple bond? Number of carbons in aspirin: Number of H atoms: (c) The drug molecule aspirin contains 8 hydrogens and 4 oxygens, and its unsaturation number is 6. How many carbons does it have?
