Double bond examples

DBE or double bond equivalent a.k.a LU or level of unsaturation is the number of unsaturations present in a organic molecule. The term unsaturation mean a double bond or a ring system. For instance, in benzene there are 3 double bonds and 1 ring which gives us 4 DBE. Moreover a tripple bond can be regarded as DBE=2. In the less complex alkenes used in earlier examples the plane of the double bond was often a plane of symmetry, and addition reagents could approach with equal ease from either side. In this case, one of the methyl groups bonded to C-6 (colored blue in the equation) covers one face of the double bond, blocking any approach from that side. A double displacement reaction is also called a double replacement reaction, salt metathesis reaction, or double decomposition.
