• molecular
  • Molecular dimers are often formed by the reaction of two identical compounds e.g.: 2A → A-A. In this example, monomer "A" is said to dimerise to give the dimer "A-A". An example is a diaminocarbene, which dimerise to give a tetraaminoethylene: 2 C(NR2)2 → (R2N)2C=C(NR2)2 Carbenes are highly reactive and readily form bonds. (wikipedia.org)
  • formation
  • For example, cellobiose is a dimer of glucose, even though the formation reaction produces water: 2C6H12O6 → C12H22O11 + H2O Here, the dimer has a stoichiometry different from the pair of monomers. (wikipedia.org)
