1. Phosphine

   Phosphine (IUPAC name: phosphane) is a colorless, flammable, highly toxic compound with the chemical formula PH3, classed as a pnictogen hydride. Pure phosphine is odorless, but technical grade samples have a highly unpleasant odor like rotting fish, due to the presence of substituted phosphine and diphosphane (P2H4). With traces of P2H4 present, PH3 is spontaneously flammable in air (pyrophoric), burning with a luminous flame. Phosphine is a highly toxic respiratory poison, and is immediately dangerous to life or health at 50 ppm. Phosphine has a trigonal pyramidal structure. Phosphines are compounds that include PH3 and the organophosphines, which are derived from PH3 by substituting one or more hydrogen atoms with organic groups. They have the general formula PH3-nRn. Phosphanes are saturated phosphorus hydrides of the form PnHn+2, such as triphosphane. Phosphine, PH3, is the smallest of the phosphines and the smallest of the phosphanes.

1. phosphine

   Phosphine is a colorless, flammable, and toxic gas with a pungent odor, composed of one phosphorus atom and three hydrogen atoms, chemically represented as PH3. It is used in various industrial applications such as in the production of flame retardants, plasticizers, and semiconductors. It is also used as a reducing agent in the pharmaceutical industry and as a fumigant in agriculture. In its pure form, phosphine is odorless, but technical grade samples have a highly unpleasant odor like garlic or rotten fish, due to the presence of substituted phosphine and diphosphine.

   Phosphine is the compound with the chemical formula PH3. It is a colorless, flammable, toxic gas. Pure phosphine is odorless, but technical grade samples have a highly unpleasant odor like garlic or rotting fish, due to the presence of substituted phosphine and diphosphane. With traces of P2H4 present, PH3 is spontaneously flammable in air, burning with a luminous flame. Phosphines are also a group of organophosphorus compounds with the formula R3P. Organophosphines are important in catalysts where they complex to various metal ions; complexes derived from a chiral phosphine can catalyze reactions to give chiral, enantioenriched products.
