Question

An organic alkane boasts a long chain structure with the molecular formula $C_{12}H_{26}$. What is its Degree of Unsaturation?

Answer: A

💡 Solution & Explanation

The formula follows the alkane general formula $C_nH_{2n+2}$ where $n=12$ ($12 \times 2 + 2 = 26$). Applying the standard DU formula: $DU = (12 + 1) - 26/2 = 13 - 13 = 0$. There are no pi bonds or rings in a fully saturated hydrocarbon.
