Final answer:
The degree of unsaturation of the given molecule with a molecular formula of C7H13O2N is 2.
Step-by-step explanation:
The degree of unsaturation of a molecule with a molecular formula of C7H13O2N can be determined by calculating the number of double bonds and rings present in the molecule. The formula for calculating the degree of unsaturation is 2n+2-H/2, where n is the number of carbon atoms in the molecule and H is the number of hydrogen atoms in the molecule. In this case, the molecule contains 6 carbon atoms (n=6) and 13 hydrogen atoms, so the degree of unsaturation can be calculated as 2(6)+2-13/2, which equals 2. Therefore, the correct answer is option c) 2.
