Calculate the degree of unsaturation for a compound with molecular formula C₉H₁₄BrCl.

Question

Quizplus · Accepted Answer

Degree of unsaturation = (2C + 2 + N - X - H)/2
C = number of carbons
N = number of nitrogens
X = number of halogens (Cl, Br, I)
H = number of hydrogens
Degree of unsaturation = (2(1) + 2 + 0 - 2 - 1)/2 = 2. Therefore, the compound has 2 degrees of unsaturation, which corresponds to either two rings, a double bond and a ring, or a triple bond.
