What is the index of hydrogen deficiency (or degree of unsaturation)for the drug lidocain?

Question

Quizplus · Accepted Answer

The formula for lidocaine is C14H22N2O. To calculate the index of hydrogen deficiency, we use the formula: (2n+2−x)/2, where n = number of carbons and x = number of hydrogens and heteroatoms. For lidocaine, we get (2(14)+2-22-2)/2 = 5, indicating 5 degrees of unsaturation or double bonds and/or rings in the molecule.
