Which among the following compounds has a degree of unsaturation equal to 5? — GOC and Organic Chemistry Basics Chemistry Question

💡 Solution & Explanation

Calculate DBE by summing the total number of $\pi$ bonds and closed rings in the skeletal structure. For example, a benzene ring contributes 4 to the DBE (1 ring + 3 $\pi$ bonds). A carbonyl double bond outside the ring would add 1 more, totalling 5.
