Phosphorus trifluoride (formula P F 3), is a colorless and odorless gas.It is highly toxic and reacts slowly with water. Its main use is as a ligand in metal complexes.As a ligand, it parallels carbon monoxide in metal carbonyls, [1] and indeed its toxicity is due to its binding with the iron in blood hemoglobin in a similar way to carbon monoxide.
Phosphorus trifluorodichloride is a chemical compound with the chemical formula PF 3 Cl 2.The covalent molecule trigonal bipyramidal molecular geometry.The central phosphorus atom has sp 3 d hybridization, and the molecule has an asymmetric charge distribution.
PGE Boiler #16 in 1988. The utility was founded in 1888 by Parker F. Morey and Edward L. Eastham as Willamette Falls Electric Company. On June 3, 1889, it sent power generated by one of four brush arc light dynamos at Willamette Falls over a 14-mile (23 km) electric power transmission line to Portland, the first US power plant to do so.
Built between 1910 and 1929 by Portland General Electric (PGE), it was added to the register in 1985. [1] In 1986, PGE gave Station L and 18.5 acres (7.5 ha) of land to the Oregon Museum of Science and Industry (OMSI). [2] The Station L turbine is a central feature of OMSI's Turbine Hall. [3]

A three-center two-electron (3c–2e) bond is an electron-deficient chemical bond where three atoms share two electrons. The combination of three atomic orbitals form three molecular orbitals: one bonding, one non-bonding, and one anti-bonding. The two electrons go into the bonding orbital, resulting in a net bonding effect and constituting a ...
