Which of the following molecular formulas represents a degree of unsaturation (Double Bond Equivalen — GOC and Organic Chemistry Basics Chemistry Question

💡 Solution & Explanation

Using $DBE = C + 1 - (H + X - N)/2$. For Benzene ($C_6H_6$), $DBE = 6+1 - 6/2 = 4$. For Xylene ($C_8H_{10}$), $DBE = 8+1 - 10/2 = 4$. For Pyridine ($C_5H_5N$), $DBE = 5+1 - (5-1)/2 = 4$. For $C_4H_4O_4$, $DBE = 4+1 - 4/2 = 3$.
