Question

What is the calculated Degree of Unsaturation for an unsaturated cyclic or acyclic compound with the molecular formula $C_5H_8$?

Answer: B

💡 Solution & Explanation

Applying the Degree of Unsaturation formula: $DU = C + 1 - H/2$. Here $C = 5$ and $H = 8$. Therefore, $DU = (5 + 1) - 8/2 = 6 - 4 = 2$. This compound could contain two double bonds, one triple bond, two rings, or one ring and one double bond.
