Rịba ama amaokwu a dị n'okpuru ma zaa ajụjụ ahụ mgbe e mesịrị n'otu asụsụ ahụ dị ka amaokwu ahụ:  Passage: Phosphine (IUPAC aha: phosphane) bụ ogige nwere usoro kemịkal PH3. Ọ bụ gas na-enweghị agba, nke na-ere ọkụ, nke na-egbu egbu, a na-edekwa ya dị ka pnictogen hydride. Phosphine dị ọcha enweghị isi, mana ihe nlele nke teknụzụ nwere isi na-adịghị mma dị ka galik ma ọ bụ azụ na-ere ere, n'ihi ọnụnọ nke phosphine na diphosphane (P2H4) nọchiri anya ya. Site na akara nke P2H4, PH3 na-enwu ọkụ na ikuku (pyrophoric), na-enwu ọkụ na-enwu ọkụ. Phosphines bụkwa otu nke organophosphorus compounds na usoro R3P (R = organic derivative). Organophosphines dị mkpa na catalysts ebe ha na-ejikọta na ion ọla dị iche iche; mgbagwoju sitere na chiral phosphine nwere ike catalyze mmeghachi omume iji nye chiral, enantio-enriched ngwaahịa.  Ajụjụ: Gịnị bụ usoro kemịkal nke Phosphine?
