What is the degree of unsaturation (DBE) of a reaction intermediate with the molecular formula ? — GOC and Organic Chemistry Basics Chemistry Question

💡 Solution & Explanation

Using the formula $DBE = C + 1 - \frac{H - N + X}{2}$, where C=8, H=6, N=2, O is completely ignored, and X=0. $DBE = 8 + 1 - \frac{6 - 2}{2} = 9 - \frac{4}{2} = 9 - 2 = 7$.
