Calculate the degree of unsaturation of the following molecules:

Question

| Organic Chemistry 2

Accepted Answer

2 rings = 2 unsaturations
4 double bonds = 4 unsat.
1 triple bond = 2 unsat.

⇒ 8 unsaturations

Degree of unsaturation = (2n_C + 2 + n_N - n_H - n_X) / 2

C₆H₄Cl₂ ⇒ Degree of unsat. = (2 x 6 + 2 + 0 - 4 - 2) / 2 = 4 unsaturations

C₆H₁₀N₂O₂⇒ Degree of unsat. = (2 x 6 + 2 + 2 - 10 - 0) / 2 = 3 unsaturations

C₈H₁₃F₂NO ⇒ Degree of unsat. = (2 x 8 + 2 + 1 - 13 - 2) / 2 = 2 unsaturations
