WebNorbornene or norbornylene or norcamphene is a highly strained bridged cyclic hydrocarbon. It is a white solid with a pungent sour odor. The molecule consists of a cyclohexene ring … WebRing-Opening Metathesis Polymerization. ROMP is initiated by transition metal compounds (typically of Ti, Ta, W, Mo, or Ru), and operates on cyclic or polycyclic olefins, opening the ring and retaining the unsaturation. Two pioneers of ROMP, Richard Schrock and Robert Grubbs, shared the 2005 Nobel Prize in Chemistry for their invention of ...
WebSep 12, 2024 · The formation of coordination compounds is one of many important aspects of inorganic chemistry. In a coordination compound, an electron pair donor, called a ligand, shares its electron pair with a metal atom. Frequently, the metal atom is a transition metal, and very commonly it is a transition metal ion, but there are other examples as well. WebPolymerization is a process through which a large number of monomer molecules react together to form a polymer. The macromolecules produced from a polymerization may …
