What is the index of hydrogen deficiency of a compound with a molecular formula of C₆H₁₂N₂?

Question

Quizplus · Accepted Answer

The index of hydrogen deficiency (IHD), also known as the degree of unsaturation, indicates the total number of pi bonds and rings in a molecule. The formula for calculating IHD is given by: IHD = (2C + 2 + N - H - X)/2, where C is the number of carbons, N is the number of nitrogens, H is the number of hydrogens, and X is the number of halogens. For the given molecular formula, which simplifies to C112H112N12S, the calculation is: IHD = (2*112 + 2 + 12 - 112)/2 = 2. This means the molecule has a total of 2 degrees of unsaturation, indicating the presence of two pi bonds, rings, or a combination thereof.
