Calculating a Degree of Unsaturation Calculations for compounds containing other elements in addition to carbon and hydrogen: Organohalogen compounds (C,H,X,where X F,Cl,Br, or 1) Add number of halogens and hydrogens to arrive at an equivalent hydrocarbon formula Replace 2 Br by 2 H BrCH2CH-CHCH2Br HCH2CH-CHCH2H C4H6Br2 “C4H8" One unsaturation: one double bond Add LeamingAl Pigh Reer时 Calculations for compounds containing other elements in addition to carbon and hydrogen: • Organohalogen compounds (C,H,X, where X = F, Cl, Br, or I) • Add number of halogens and hydrogens to arrive at an equivalent hydrocarbon formula Calculating a Degree of Unsaturation
